While studying at Columbia, Johnson started his formatted show, Equals Three, as a way to combine two popular video styles: watching viral videos and video bloggers. In Equals Three, Johnson reviewed, criticized and added commentary to some of the internet's latest viral videos. Equals Three episodes are usually uploaded to his channel every Tuesday. Equals Three is on one of the most subscribed channels on YouTube, having more than 10.6 million subscribers in December 2013 and has been recognized by Guinness World Records.

In January 2011, Johnson launched a collaborative YouTube channel called "YourFavoriteMartian" (YFM), which features animated music videos. The songs are performed by a virtual band of four fictional cartoon characters: PuffPuff Humbert (vocals, voiced by Johnson), DeeJay (turntables), Axel Chains (drums) and Benatar (vocals, guitar/keytar/bass/piano, voiced by Jesse Cale). Johnson writes lyrics, raps, sings, composes beats, and sometimes collaborates with other musicians to produce the songs. In August 2013 the channel had over 2.2 million subscribers.

In May 2013, Johnson announced he signed a deal to produce a sitcom for the American television network FX.

On December 12, 2013, Johnson released a 5-part web series titled Riley Rewind, which he directed and starred in. It is the story of a high school student who has the ability to rewind time. After the suicide of another student at her school, she attempts to change time and save her life.
