The show reverted to the traditional format (1 GMM video + GMMore) upon the beginning of Season 14. No other changes to the format have been made since.
On December 13, 2013, Rhett & Link made a new YouTube channel called Good Mythical MORE. The videos are extensions of Good Mythical Morning episodes. They are often in a more laid-back non-edited fashion, often just talking about the primary episode, their lives, or just chilling out with the staff (known as the "Mythical Crew"). The format, however, has changed in the recent seasons, now edited, and as a regular extension to GMM. They now reveal the "Wheel Of Mythicality" ending at the start of each GMMore episode.
It is a cooking channel primarily hosted by one of the Mythical Crew members and the “Mythical Chef,” Josh Scherer, which focuses everything related to food. It features recipe videos that are uploaded every week as well as various food shows like “Fancy Fast Food”. The new channel launched on January 13, 2020, along with the 17th season of Good Mythical Morning.
It was initially a channel that was dedicated entirely to the Mythical Crew and was named as This Is Mythical and later as simply Mythical. Before this, it was also a secret behind-the-scenes channel for Rhett and Link.
On September 27, 2013, Rhett and Link launched Ear Biscuits on iTunes, Spotify and SoundCloud. The podcast debuted in the US on the iTunes charts at No. 22. and it is described as intimate discussions with each other such as how they became blood brothers, their close encounters with death, and more. They have interviewed other notable Internet personalities including Grace Helbig, Julian Smith, Philip DeFranco, PewDiePie, and Rainn Wilson. The show has had live recordings on VidCon as well as Rhett-and-Link-only episodes each month.
The show won a Shorty Award for Best Podcast in April 2016.
On March 27, 2017, the podcast returned from a hiatus with a new video format on their latest channel, This Is Mythical, and has moved to the Good Mythical Morning channel. The podcast continues to be released on iTunes and Soundcloud, as well as Spotify.
On January 7, 2019, the podcast was moved from the Good Mythical Morning channel to its own separate channel.
On November 18, 2014, Rhett & Link cast two other YouTubers, Shannon Coffey and Candice Carrizales, to create The Hey Hey Show. The Hey Hey Show started similar in concept but changed overtime before eventually ending.
On June 29, 2012, Rhett and Link would soon be completing Season One of Good Mythical Morning after a whopping one hundred twenty-nine episodes. Following the clip-show style episodebest of GMM Season One, the season ended.
Replacing it for a month, however, would be another show entitled RLVault.
The show, shot on the same set as Mythical Morning, looked back at older videos from Rhett and Link's main channel and gave a new perspective on them. Joyfully, fans returned to Good Mythical Morning on August 6, 2012, to be greeted by a new animated intro, theme, and fun stories from Rhett and Link.
In addition to the new theme and opening, the format was given minor tweaks for Season Two, such as a makeover for the Wheel of Mythicality, the wheel that tells Rhett and Link how to end the show. The Wheel now bears three colored show endings, one blue, one red, and one black. Rhett and Link don't know about these three endings beforehand, leading to some level of mystery about what will happen. The blue and red colors represent positive endings, while black represents something negative.
Season Two also featured many new segments. Thursdays became the day for reading mail and social media posts; most of the former would eventually end up in their Mythical Time Capsule. Also scheduled for Thursday was a two to three-minute puppet show starring high-quality, fan-built puppet incarnations of the two, known as the "Time Rangerers." A week of episodes also occurred in which Link was absent due to a family gathering, and to compensate, Rhett brought on guest hosts, namely SourceFed's Joe Bereta, Rhett's children, and the infamous taxidermist Chuck Testa.
The season ended on November 30, 2012, with a compilation episode of the season's greatest moments.
Season Three of Good Mythical Morning premiered on January 14, 2013. Season Three, the shortest of the three seasons, running for just 62 episodes, ended on April 5, 2013.
The format for the episodes stayed almost the same, with a few minor tweaks. Two new spots were added to the Wheel of Mythicality, "Link's Choice," and the black and blue spots remained with the same function as before they were kids.
Also, mid-season, Rhett and Link moved to a new set that functioned as the duo's headquarters and the workplace of new interns who occasionally make cameos in the filming of the show. Season three also became the premiere season for the rock to which Rhett would glue small items sent to their P.O. Box, and would continually grow based on the number of items.
Thursdays on the show also became dedicated to mail, bringing back former rhettandlink2 segment "Friday Means Mail," of course, with the day changed, and posts from Facebook, Twitter, etc. in a way similar to Season Two's Mythical Perspective day.
The show, unfortunately, ended the season after twelve weeks, on April 5, 2013, following the announcement of an upcoming project, The Mythical Show, which would also be released on their second channel. Despite the project filling the time slot, Rhett and Link announced the twelve-minute talk show. Furthermore, the final episode became the first finale not to be a clip show-style episode. It featured an episode called "Good Mythical Morning Trivia Game," in which Rhett and Link both answered trivia questions. See full page: Mythical Christmas Special
Following the season two finale, Rhett and Link returned to the "Good Mythical Morning" set for a half-hour Christmas special, which they called Mythical Christmas Special. The special included most "Good Mythical Morning" segments, bringing back the Speech Jammer, among other things, and inspired Rhett and Link's The Mythical Show with its long-form variety show format.
Season Ten of Good Mythical Morning premiered on August 1st, 2016.
The 1000th episode of Good Mythical Morning premiered on October 13th, 2016, featuring tributes from various YouTubers such as Smosh, IISuperwomanII, Epic Rap Battles of History, Tyler Oakley, TayZonday, Rosanna Pansino, Hannah Hart, Flula Borg, and the Fine Brothers.
