Politico has hailed Maher as "a pugnacious debater and a healthy corrective to the claptrap of cable news," while Variety noted, "There may not be a more eclectic guest list on all of television."

Maher headlined his first special on the network in 1989 and has starred in ten solo specials to date, including the hour-long presentations "Bill Maher: Live from D.C.," "Bill Maher... But I'm Not Wrong," "The Decider" and "I'm Swiss" (both nominated for an Emmy(R) in the Outstanding Variety, Music or Comedy Special category), "Victory Begins at Home," "Be More Cynical," "The Golden Goose Special" and "Stuff That Struck Me Funny," and two half-hour stand-up specials, plus the specials "30 Seconds Over Washington" and "Comic Relief VI(TM)." Maher is also an executive producer of the innovative news magazine show "VICE," which is now in its third season on HBO.

Maher was the creator and host of "Politically Incorrect," which was produced by HBO Downtown Productions and debuted on Comedy Central in 1993. The series moved to ABC in 1997 and ran through 2002. He also produced and starred in the 2008 feature film "Religulous," the seventh most successful documentary of all time.

The executive producers of REAL TIME WITH BILL MAHER are Bill Maher, Scott Carter, Sheila Griffiths, Marc Gurvitz, Brad Grey, Billy Martin and Dean E. Johnsen; produced by Matt Wood; director, Paul Casey.
