Blippi

John was criticized in 2019 when he performed a "bait and switch", advertising a Blippi tour for which parents paid hundreds of dollars, but not making it clear that Blippi would not be played by him, but by an impersonator.

Stevin John served active duty in the United States Air Force as a loadmaster for the C-17 Globemaster airplane at the 4th Airlift Squadron and is a military veteran. His duties were to perform the calculations and planning cargo placement to keep the aircraft within permissible center of gravity limits throughout the flight.

The idea for Blippi came to Stevin John after moving back to Ellensburg, and witnessing his then two-year-old nephew viewing low-quality videos on YouTube. Blippi has been described as, "an adult human man who dresses up in bright clothes and dances around America’s deserted soft play centres for the benefit of YouTube". The first Blippi video was published on January 27, 2014, with John starring as Blippi and doing all of the filming, editing and graphics himself on the initial videos. Taking inspiration from children's educators and entertainers before him, such as Mr. Rogers, John wished to portray Blippi as educational, but also as thinking and acting as a child would.

Stevin John initially started making gross out videos in 2013 under the persona of Steezy Grossman, a boy born as poop resulting from anal intercourse. Under his Steezy Grossman alias, John developed videos such as "Turdboy" and "Underwear Man". In a 2013 video John performed the Harlem shake on a toilet and defecated on a naked friend. When the video was unearthed by Buzzfeed in 2019, John said, "at the time, I thought this sort of thing was funny, but really it was stupid and tasteless, and I regret having ever done it." John used DMCA takedown notices to remove the video from social media and internet search engines.

Stevin John (born May 27, 1988 as Stephen J. Grossman), better known by his alias Blippi, is an American children's entertainer and educator on YouTube and Amazon Video. The Blippi videos are intended to be educational and appeal to young children, as John's Blippi character is portrayed with a childlike, energetic and curious persona; always dressed with his blue and orange beanie cap, blue shirt, orange suspenders and a bow tie. Grossman was also revealed as a former gross out comedian, known as Steezy Grossman.
