Talk show host, game show host, comedian, magazine anchor and executive producer would all be acceptable titles for Mark Walberg, a man who started his television career as a gofer at Dick Clark Productions, Inc. It was while working as an assistant there that Walberg had the opportunity to fill in for the comedian who was supposed to warm up the studio audience.

It wasn't long before Walberg was on camera as the announcer/sidekick on the game show Shop 'til You Drop. He soon moved on to hosting Burnt Toast, an extreme sports magazine show on ESPN. It was there that the late Brandon Tartikoff noticed his work, and in 1995, The Mark Walberg Show debuted in syndication. It was the first program to be launched under the new alliance of stations from FOX and New World Entertainment.

Currently Walberg hosts PAX's nightly game show On the Cover. He is also well known to fans of reality television for his hosting work on the popular series Temptation Island. His other hosting credits include Russian Roulette, Anything For Love and Test the Nation. He appeared in the ABC Family Movie of the Week I Want to Marry Ryan Banks. Other credits include playing himself on an episode of Son of the Beach, as well as competing in and winning a celebrity TV host edition of The Weakest Link.

Walberg partnered with television personality Mark DeCarlo to form the GlugginMarx television production company. Together they produced Sunday Dinner. In addition, GlugginMarx has produced the comedy/game show pilot The Jack Cash Show with Studios USA and the relationship/talk show The Game for Telepictures Productions.

Walberg also serves on the board of Goodwill Industries of Southern California and the Hollywood Wilshire YMCA.
