In October 2004, Mike Mizanin entered the fourth season of Tough Enough, a televised competition which awarded the winner a World Wrestling Entertainment (WWE) contract and $1,000,000. Despite coming last in an arm wrestling tournament on November 25, Mizanin outlasted six other wrestlers and reached the final round. At Armageddon, Mizanin faced the other remaining entrant, Daniel Puder, in a three-round "Dixie Dogfight" (boxing match). Neither man achieved a knockout, and the contest was awarded to Puder on the basis of crowd reaction. On the December 16 episode of SmackDown, Puder was declared as the winner of Tough Enough by head trainer Al Snow.
In July 2005, he wrestled two dark matches for WWE, teaming with former Tough Enough champion Matt Cappotelli to face The Highlanders (Robbie and Rory McAllister).
From March 7, 2006 onwards, a video on WWE's website and vignettes on SmackDown heralded The Miz debuting on SmackDown. When Mizanin actually attempted to make his debut on the April 21 episode of SmackDown, he was in storyline banned from entering the arena by network executive Palmer Canon who told him that he had been "cancelled" before having security escort him from the premises.
The Miz debuted as SmackDown's host on June 2, hyping up the crowd at the top of the show. Other duties included backstage interviews and hosting a bikini contest. Starting in July, Miz, along with Ashley Massaro, hosted the annual Diva Search competition. After the end of the Diva Search competition, The Miz returned exclusively to SmackDown as a villain, making his in-ring debut with win over Tatanka on the September 1 episode of SmackDown!. Over the next three months, The Miz remained undefeated, defeating such wrestlers as Matt Hardy, Funaki and Scotty 2 Hotty. At the same time he began a feud with Diva Search winner Layla El, who spurned his advances on more than one occasion, leading to Miz helping Kristal defeat her in various competitions. However, Miz and Kristal soon found themselves being stalked by The Boogeyman. This began a feud in which the Boogeyman ended The Miz's winning streak at December's Armageddon event.
The Miz took part in the 2007 Royal Rumble match from entry #29, but was immediately thrown out by The Great Khali, lasting only seven seconds. Following a brief absence from television, The Miz returned to SmackDown to host an interview segment named Miz TV. After the unsuccessful segment, The Miz returned to in-ring competition with a more intense style and began to pick up wins once again.
Miz was drafted from SmackDown to ECW on June 17 as part of the 2007 supplemental draft. He was absent from the first few weeks of ECW, though he was the subject of backstage mentions between matches and had several short Miz TV Crashes ECW video segments. He made his debut on the July 10 episode of ECW in a match against Nunzio, which he won.
Soon after, The Miz found new managers in Kelly Kelly, Layla El and Brooke Adams. He then began a feud with Balls Mahoney after Kelly Kelly began to fall in love with Mahoney on screen. On the October 2 episode of ECW, it was revealed that Miz owned the contracts of Kelly Kelly, Layla and Brooke Adams; and he used this excuse to stop Kelly from going out with Mahoney. He was voted at Cyber Sunday to face CM Punk for the ECW Championship, but lost the match.
On the November 16 episode of SmackDown!, The Miz became one half of the WWE Tag Team Champions with John Morrison when they defeated Matt Hardy and Montel Vontavious Porter, giving Miz his first championship within the company. At Survivor Series, Miz and Morrison competed in a triple threat match for the ECW Championship, with the champion CM Punk retaining.
In February 2008, Miz and Morrison were given a streaming segment on the WWE website named The Dirt Sheet in which they mocked other wrestlers and facets of pop culture, showing off their promo skills. Morrison and The Miz co-wrote each episode of The Dirt Sheet each week. Miz competed in a battle royal on the pre-show of WrestleMania XXIV, but was unsuccessful in winning after being eliminated by Jamie Noble. The team of Miz and Morrison had many successful title defenses over the next few months before dropping the championship to Curt Hawkins and Zack Ryder at the Great American Bash in a fatal four-way match which also involved Jesse and Festus and Finlay and Hornswoggle. Neither Miz nor Morrison were pinned as Hawkins pinned Jesse to win the titles. Miz and Morrison soon followed their tag title loss with a feud with Cryme Tyme (Shad Gaspard and JTG), with a battle of their webshows, Word Up and The Dirt Sheet being a catalyst. They were voted into a match with, and defeated, Cryme Tyme at Cyber Sunday. The team also feuded with D-Generation X (Triple H and Shawn Michaels), using phrases such as "Are you 50?" instead of DX's usual catchphrase "Are you ready?" to mock their ages due to DX being formed in 1997, when both Miz and Morrison were in high school. On the 800th episode celebration of Raw, Miz and Morrison competed in a match against DX, and were defeated. During the match, they mocked DX's signature moves, with Morrison successfully performing a superkick (mocking Michaels' Sweet Chin Music) on Triple H. On December 13, Miz and Morrison defeated Kofi Kingston and CM Punk to win the World Tag Team Championship during a WWE house show in Hamilton, Ontario, Canada.
In February 2009, the team engaged themselves in a feud with The Colóns (Carlito and Primo). In a dark match at WrestleMania XXV, they lost the World Tag Team Championship to The Colóns in a lumberjack match to unify the World Tag Team and the WWE Tag Team titles. On the April 13 episode of Raw, The Miz lost a match to Kofi Kingston due to Morrison's inadvertent interference, which gave Raw a draft pick in the 2009 WWE draft. The pick was then revealed to be The Miz and retaliated by subsequently attacking Morrison, ending their partnership and thus turning John Morrison into a fan favorite.
Miz challenged John Cena to a match on the April 27 episode of Raw, but as Cena was out due to injury, Miz claimed an unofficial win via forfeit and continued to do this over the following weeks, until Cena returned and defeated him in a singles match at The Bash in June. On the August 3 episode of Raw, The Miz lost a match to Cena, which meant that, in storyline, he was banned from the Staples Center, the Raw brand and SummerSlam. The following week on August 10, Miz competed under a mask as The Calgary Kid and won a Contract on Pole match against Eugene, earning a contract in storyline, and revealing himself by removing his mask afterwards. He then debuted his new finisher, the Skull-Crushing Finale, and used it on Eugene. After removing the mask to reveal himself, he cut a promo and debuted his catchphrase: "Because I'm The Miz... and I'm awesome".
Miz would then set his sights on the United States Championship. He unsuccessfully challenged for the championship at the Night of Champions, Breaking Point and Hell in a Cell pay-per-views, before he won the championship on the October 5 episode of Raw, by defeating Kofi Kingston - his first singles championship in WWE. At the following pay-per-view event, Bragging Rights, Miz was inserted into an interpromotional match against SmackDown's Intercontinental Champion, Miz's erstwhile tag team partner John Morrison. At the event on October 25, Miz defeated Morrison. The following month at Survivor Series, Miz captained a team of five wrestlers against Team Morrison in a five-on-five Survivor Series elimination match and once again bested his former partner surviving with Sheamus and Drew McIntyre.
In January 2010, The Miz began a rivalry with MVP that began with a critically well-received verbal exchange between the two. The two met in an unadvertised match for the United States Championship at the Royal Rumble event with Miz retaining his title, but in the Royal Rumble match itself MVP eliminated both himself and The Miz. During this time, Miz formed a tag team with Big Show — later dubbed "ShoMiz" — and on the February 8 episode of Raw the two defeated D-Generation X and The Straight Edge Society to become the Unified WWE Tag Team Champions, making Miz the first wrestler in WWE history to hold three championships at the same time (United States, World Tag Team and WWE Tag Team Champion). At Elimination Chamber, Miz again successfully defended his United States Championship against MVP after interference from Big Show, ending their feud.
Miz appeared on the NXT show as the storyline mentor of Daniel Bryan. At WrestleMania XXVI on March 28, ShoMiz defeated John Morrison and R-Truth to retain the title again. At Extreme Rules on April 25, ShoMiz lost to The Hart Dynasty in a gauntlet match, which per the match stipulation gifted them a tag team title opportunity, which they would receive the following night on Raw, in which ShoMiz lost the titles. After the match, Big Show knocked Miz out and was later drafted to the SmackDown brand, dissolving the team.
On the May 10 episode of Raw, Tyson Kidd defeated The Miz in a match, which earned any member of The Hart Dynasty a match for the United States Championship and The Miz, who was allowed to choose his opponent, elected to face Bret Hart. On the following episode of Raw on May 17, Hart defeated The Miz to win the United States Championship, despite Chris Jericho, William Regal and Vladimir Kozlov attempting to interfere on The Miz's behalf. The Miz had a tumultuous relationship with Bryan, who was eliminated from NXT on May 11, although he returned the following week to attack The Miz.
The Miz returned as a Pro for the second season of NXT, to mentor Alex Riley, the only Pro to return. On the June 14 episode of Raw, The Miz defeated R-Truth, John Morrison and Zack Ryder in a fatal four-way match to win the United States Championship for the second time and retained the championship against R-Truth at the Fatal 4-Way pay-per-view.
On July 18 at the Money in the Bank pay-per-view, The Miz won a Money in the Bank ladder match to win a contract for a WWE Championship match that he could utilize at any time over the next year and became the first performer to win Money in the Bank while being a champion and the second, after Rob Van Dam, to hold a Money in the Bank contract and a title at the same time. Over the next few weeks, The Miz attempted to cash in his Money in the Bank contract on the WWE Champion Sheamus, but was continually interrupted by other wrestlers before the matches could occur, which meant that he retained the contract for future use. Daniel Bryan returned to WWE at SummerSlam, taking The Miz's place on Team WWE, causing The Miz to attack him mid-match, which would result in Bryan's eventual elimination from the match. This began a rivalry between the two, with The Miz losing the United States Championship to Bryan at the Night of Champions event in September. In October, Miz defeated John Cena (after interference from Husky Harris and Michael McGillicutty) to become the captain of Team Raw, but Team Raw (composed of Miz, R-Truth, John Morrison, Santino Marella, Sheamus, CM Punk and Ezekiel Jackson) were unsuccessful in defeating Team SmackDown at the Bragging Rights pay-per-view.
On the November 22 episode of Raw, he cashed in his Money in the Bank contract following a successful WWE Championship defense by Randy Orton against Wade Barrett to become the new WWE Champion. The following week, Miz made his first successful title defense, defeating Jerry "The King" Lawler in a Tables, Ladders and Chairs match after interference from Michael Cole. He successfully defended the championship at the TLC: Tables, Ladders & Chairs pay-per-view in December by defeating Orton in a tables match following interference from Alex Riley. Miz would then successfully defend the championship against Orton again at the Royal Rumble (after interference from CM Punk) and Lawler the following month at Elimination Chamber in 2011. The night after Elimination Chamber, The Miz and John Cena were paired together by the Anonymous Raw General Manager to challenge The Corre (Justin Gabriel and Heath Slater) for the WWE Tag Team Championship. The Miz and Cena were successful in winning the titles, but lost them back to Corre immediately afterward in a rematch after The Miz turned on Cena. This made their reign the shortest in the championship's history. The following week, The Miz lost Riley as his apprentice after Cena defeated Riley in a steel cage match with the stipulation that if Cena won, Riley was fired from his job. However Riley would be re-hired in mid-March, this time as Miz's "Vice President of Corporate Communications". In the main event of WrestleMania XXVII on April 3, The Miz successfully defended the WWE Championship against Cena, following interference from The Rock, who then attacked Miz afterwards. At Extreme Rules on May 1, The Miz lost the WWE Championship to Cena in a triple threat steel cage match, also involving John Morrison. The Miz would receive his rematch the next night on Raw, which he initially won to regain the championship after hitting Cena with the title belt; however, the decision was reversed after Riley accidentally revealed the title to the referee, resulting in Miz being disqualified. He then failed to regain the championship from Cena again in an "I Quit" match at Over the Limit on May 22, after botched interference from Riley.
The following night on Raw, the Anonymous Raw General Manager denied The Miz's request for another WWE Championship match; Miz blamed Riley for being unable to regain the championship. Riley then attacked him, turning Riley into a fan favorite. At Capitol Punishment on June 19, Miz faced Riley in a losing effort. The Miz lost Raw's Money in the Bank ladder match at the titular event as the match was won by Alberto Del Rio. After the WWE Championship was declared vacant by Vince McMahon, Miz would enter into a tournament to crown a new champion, defeating Riley and Kofi Kingston to advance to the finals, where he lost to Rey Mysterio. At SummerSlam in August, Miz teamed with R-Truth and Alberto Del Rio to face Mysterio, Kingston and John Morrison in a losing effort.
On the August 22 episode of Raw, Miz and R-Truth attacked Santino Marella before his match. They then cut a promo agreeing there was a conspiracy in the WWE keeping both of them out of the main event picture, and declared they would, together, seize any future opportunity. They began referring to themselves as "The Awesome Truth". At Night of Champions, after the referee was distracted while The Miz attempted a pin, Miz assaulted him, causing Awesome Truth to lose a WWE Tag Team Championship match to Air Boom (Kofi Kingston and Evan Bourne) by disqualification. Seeking retribution, Miz and Truth later attacked both Triple H and CM Punk during their No Disqualification match in the main event. Because of their actions from the previous night, R-Truth and The Miz were fired by Triple H on the September 19 episode of Raw. At the conclusion of the main event match at Hell in a Cell, R-Truth and The Miz jumped the barricade wearing black hooded sweatshirts and entered the cell as it was being raised. They then used weapons to attack Alberto Del Rio, CM Punk, John Cena, the referee and camera men while the cell was again lowered. After this, the entire WWE roster led by Triple H came out to find a way into the cell, before New Orleans Police Department officers were able to get the door open and arrest them. The two later posted a video on YouTube apologizing to the fans for their actions. The Miz and R-Truth were reinstated by John Laurinaitis on the October 10 episode of Raw. At Vengeance, Miz and R-Truth defeated CM Punk and Triple H in a tag team match, after interference from Triple H's long time friend Kevin Nash. Later that night they assaulted John Cena during his WWE Championship match with Alberto Del Rio. At Survivor Series in November, The Awesome Truth were defeated by John Cena and The Rock. On the November 21 episode of Raw, Cena instigated an argument between R-Truth and Miz, which resulted in Miz performing a Skull Crushing Finale on the stage on R-Truth. This was a pretext to explain R-Truth's absence during his suspension as a result of his violating of the Wellness Policy.
On the November 28 episode of Raw, Miz defeated John Morrison in a Falls Count Anywhere match after a Skull Crushing Finale on the stage. On the December 5, episode of Raw, Miz qualified for a triple threat Tables, Ladders and Chairs match against Alberto Del Rio and CM Punk at the TLC: Tables, Ladders & Chairs pay-per-view for the WWE Championship after a win over Randy Orton via countout, but was unsuccessful.

Miz picked up the win for Team Johnny after pinning Zack Ryder with the help of Eve, ending his twenty-match losing streak dating back to 2011.

The following month at Super Showdown, Miz competed in the 51-man battle royal, but did not win. In July, Miz restarted his feud with Dolph Ziggler after a confrontation on "Miz TV". A match between the two was arranged for SummerSlam, however during the contract signing on the August 5 episode of Raw, Miz revealed that he was not Ziggler's opponent, instead it was the returning Goldberg who would take Miz's place in the match. The night after SummerSlam, Miz defeated Ziggler to end their feud. Miz then competed in the 2019 King of the Ring, but was eliminated in the first round by Baron Corbin. Miz then unsuccessfully challenged for Shinsuke Nakamura's Intercontinental Championship at Clash of Champions in September, after interference from Nakamura's manager Sami Zayn.
As part of the 2019 draft, Miz was drafted to SmackDown. During the November 1 episode of SmackDown, NXT wrestler Tommaso Ciampa disrupted an edition of Miz TV to air his grievances towards Miz, accusing him of being self-centered. He subsequently challenged Ciampa to a match, which he would lose via pinfall. The following month, Miz began a feud with Universal Champion Bray Wyatt, who, under his sinister alter ego "The Fiend", proclaimed he wanted to become part of Miz's family. He would later attack Miz backstage as well as terrorize Miz’s daughter. Subsequently, a non-title match between Miz and Wyatt was arranged for the TLC pay-per-view. At the event, The Miz was defeated by Wyatt. On the January 3, 2020 episode of SmackDown, Miz blindsided Kofi Kingston after being defeated in a match against him and subsequently lashed out at the audience after being booed, turning heel in the process.
On the following episode of SmackDown, he reunited with the returning John Morrison on Miz TV, in which Morrison insulted the audience for booing Miz. Subsequently, Morrison helped Miz win his rematch against Kingston. Miz next participated in the 2020 Royal Rumble match on January 26 at entrant number seventeen, but was eliminated by Drew McIntyre. At Super ShowDown, Miz and Morrison defeated The New Day to win the WWE SmackDown Tag Team Championship, using dirty tactics. At Elimination Chamber on March 8, Miz and Morrison retained the championship over The New Day, The Usos, Heavy Machinery (Otis and Tucker), Lucha House Party (Gran Metalik and Lince Dorado) and Dolph Ziggler and Robert Roode in a tag team Elimination Chamber match. Miz and Morrison were originally set to defend the championship in a triple threat tag team ladder match against The New Day and The Usos at WrestleMania 36, but Miz pulled out of the event due to illness. Instead, Morrison individually defended the championship in a triple threat ladder match against Kofi Kingston of The New Day and Jimmy Uso of The Usos, which Morrison won. On the April 17 episode of SmackDown, the duo lost the titles back to The New Day after Miz unsuccessfully defended the titles by himself in a triple threat match against Big E and Jey Uso. At Money in the Bank the following month, Miz and Morrison unsuccessfully attempted to regain the championships in a fatal four-way tag team match also involving Lucha House Party (Gran Metalik and Lince Dorado) and The Forgotten Sons (Steve Cutler and Wesley Blake). Afterwards, Miz and Morrison began a rivalry with Universal Champion Braun Strowman. At Backlash, the duo competed for Strowman's title in a two-on-one handicap match, but lost.
As part of the 2020 draft in October, both Miz and Morrison were drafted to the Raw brand. Before the draft, The Miz and John Morrison were feuding with Heavy Machinery. The feud involved Miz sending Otis’ girlfriend Mandy Rose to the Raw brand. On the October, 23 episode of SmackDown, they were involved in a court case due to The Miz believing Otis wasn’t suited to holding the Money in the Bank briefcase. After The Miz bribed the judge, JBL in a judge's smock, he was given a match at Hell In A Cell against Otis for the briefcase. At the event, Miz defeated Otis after Tucker hit him with the briefcase. The Miz cashed in his Money in the Bank contract at the TLC: Tables, Ladders & Chairs event during a TLC match match between AJ Styles and WWE Champion Drew McIntyre, making the match a triple threat in the process, but was unsuccessful as McIntyre retained his title. However, on the December 28 episode of Raw, Miz had the contract returned to him as the cash-in at TLC was ruled invalid due to Morrison cashing in the contract on his behalf (as only the contract holder himself can cash it in). The Miz would go on to enter the Royal Rumble match, but was eliminated by the debuting Damian Priest after a distraction from Bad Bunny, whom Miz and Morrison had gotten into an altercation with earlier in the night. The Miz was then announced as a participant in the Elimination Chamber match for the WWE Championship at the namesake pay-per-view; he later withdrew himself from the match in a failed attempt to replace himself with John Morrison. At Elimination Chamber, The Miz would successfully cash in on WWE Champion Drew McIntyre and win the title for the second time in his career. However, Miz would lose the championship to Bobby Lashley on the March 1 episode of Raw, ending his reign at only eight days. After this, Miz and Morrison continued feuding with Bad Bunny and Damian Priest. At WrestleMania 37 in April, Miz and Morrison were defeated by Bad Bunny and Priest. At WrestleMania Backlash, Miz lost to Damien Priest. During the match, Miz suffered the first legitimate injury in his WWE career after tearing his ACL, taking him out of action indefinitely; he appeared on television in a wheelchair alongside John Morrison on the June 7 episode of Raw.
Miz returned from injury on the August 16 episode of Raw, losing to Damian Priest. The next week on Raw, Miz attacked Morrison, ending their partnership. Afterwards, Miz took extended time off. He, along with Maryse, returned on the November 29 episode of Raw, where he confronted Edge. The following week on Raw, after another heated verbal exchange between the two during a Miz TV segment, Miz challenged Edge to a match at Day 1, and Edge accepted. At Day 1, Miz lost to Edge. The following week, The Miz accepted a challenge by Edge and Beth Phoenix for a mixed tag team match at the Royal Rumble against him and Maryse. At the event, they lost to Edge and Phoenix. At WrestleMania 38, Miz partnered with social-media star Logan Paul in a winning effort against the The Mysterios. After the match, Miz preformed his finishing maneuver, the Skull Crushing Finale, on Logan Paul, subsequently turning on him. They then began a feud which led to a match between the two at SummerSlam, which Paul won. On the August 8 episode of Raw, Miz lost to AJ Styles in a no disqualification match. On the August 22 episode of Raw, Miz was kidnapped by Dexter Lumis, who continued to attack him over the following weeks. He challenged Bobby Lashley for the United States Championship in a steel cage match on the September 5 episode of Raw, but lost after Lumis interfered. At the Royal Rumble on January 28, 2023, Miz entered the Royal Rumble match at number three, but was eliminated by Sheamus. On the February 20 episode of Raw, during the celebration of their anniversary, Maryse handed The Miz an envelope with the Miz promising to reveal its contents on the following episode of Raw. This led to The Miz being named the official host of WrestleMania 39. At the event, Miz lost impromptu matches against Pat McAfee and Snoop Dogg, the latter replacing an legitimately injured Shane McMahon early in the bout. On April 3, Matt Riddle returned on the Raw after WrestleMania 39 by attacking The Miz.
On the June 19 episode of Raw, Tommaso Ciampa returned to answer The Miz's open challenge, which Ciampa won, thus ending their alliance and turning Ciampa face once again. On the July 11 episode of Raw, Miz received his first win of 2023, defeating Ciampa in a no disqualification match with the help of Bronson Reed. On the October 30 episode of Raw, The Miz turned face for the first time since 2020 after cutting a promo against the Intercontinental Champion Gunther. The following week, Miz won a fatal four-way match to earn a title match against Gunther at Survivor Series. At the event on November 25, Miz failed to win the title from Gunther. Miz challenged Gunther for the title again on the December 18 episode of Raw in a losing effort and, per the stipulation, could not challenge for the title again as long as Gunther remained champion.
On the Day 1 episode of Raw, Miz reunited with former partner R-Truth in a winning effort against Dominik Mysterio and JD McDonagh of the Judgment Day. At the Royal Rumble on January 27, Miz entered the men's Royal Rumble match at number twenty-five, lasting six minutes before being eliminated by Gunther. On the following episode of Raw, Miz attempted to save R-Truth from an attack by The Judgment Day, only to be beaten down by the group. On the March 18 episode of Raw, Miz and Truth defeated Indus Sher (Veer and Sanga) to qualify for the six-pack ladder match for the Undisputed WWE Tag Team Championships at WrestleMania XL. On night one of WrestleMania XL on April 6, Truth climbed the ladder and retrieved the Raw Tag Team Championship to win the titles, giving Miz his first title win since 2021. On the April 15 episode of Raw, Triple H unveiled the new World Tag Team Championship belts, which replaced the Miz and R-Truth's Raw Tag Team Championships. On the April 22 episode of Raw, Miz and Truth successfully defended their tag titles in their first title defense against #DIY (Johnny Gargano and Tommaso Ciampa). On the April 29 episode of Raw, Miz and Truth defeated Alpha Academy (Otis and Akira Tozawa) to retain their titles.

On the June 10 episode of Raw, Miz and Truth defeated Authors of Pain ( Akam and Rezar) to successfully retain the tag titles after a distraction from The New Day. On the June 24 episode of Raw, Miz and Truth lost the titles to Bálor and McDonagh after interference from Carlito, Dominik Mysterio and Liv Morgan, ending their reign at 79 days.
On August 3, The Miz served as the official host of SummerSlam in Cleveland. On the September 30 episode of Raw, The Miz kicked R-Truth and walked out on him, causing the team to lose against The Authors of Pain, turning heel once again and disbanding The Awesome Truth in the process.
