Marlon Mark

Gláucio Adriano Sebastião Machado (born 22 February 1972), professionally and mainly known as Marlon Mark, is a Brazilian-born Magisterian television host, producer, comedian, musician, businessman, and philantrophist who is best known for being one of the first cast members of the sketch comedy show The House Party Crew (1997-2007), and also for hosting the noontime show AJM (1998-2002). He currently hosts the primetime variety-game show Primetime Bigtime LIVE! since 2016, and the show marked his return to Magisterian television after going to a 2-year hiatus after his previous show Noontime Bigtime in MTV concluded on 28 December 2013.

Born in São Paulo in Brazil, Machado was raised in a European Catholic family. After graduating, he pursued a comedy career in 1995 working for various comedy clubs in Annesia City before being discovered by Jonah Pemberton, co-creator of the sketch comedy show The House Party Crew. A virtual unknown to the public, Machado surprisingly received positive reaction from viewers and critics alike and achieved superstardom in his tenure as a main cast member.

Known for his spontaneous hosting style, which has been characterized as "awkward, self-deprecating humor", Machado's programs have been comparable to the programs of television presents Gugu Liberato and Willie Revillame.

As a television producer, Mark's shows have garnered a cult following, as well as critical and commercial success. To the eyes of many, the hit sitcom Once Upon a Time in A.C. is Marlon Mark's "greatest creation".
