From Wikipedia:
The Larry Sanders Show was an American television sitcom set in the office and studio of a fictional late-night talk show. The show was created by Garry Shandling and Dennis Klein and aired from August 1992 to May 1998 on the HBO cable television network. The series stars Shandling, Jeffrey Tambor, and Rip Torn and features celebrities playing exaggerated, self-parodying versions of themselves. The show has its roots in Shandling's stand-up comedy background, his experience as a guest host on The Tonight Show and his earlier sitcom It's Garry Shandling's Show. The program has had a marked and long-lasting influence on HBO as well as on television shows in America and Britain such as Curb Your Enthusiasm, 30 Rock and The Office. The supporting cast includes Janeane Garofalo, Bob Odenkirk, Kathryn Harrold, Scott Thompson and Jeremy Piven.
Regarded as an influential and landmark series, it ranked 38 on TV Guide's 50 Greatest TV Shows of All Time, the only HBO comedy to make the list, and was also included in Time magazine's list of the "100 Best TV Shows of All Time."
The show won 24 major awards, including three Primetime Emmy Awards, five CableACE Awards, four American Comedy Awards, two British Comedy Awards, two Peabody Awards, a BAFTA Award and a Satellite Award. It also received 86 nominations, including 56 Primetime Emmy Awards nominations, five Directors Guild of America nominations, six Writers' Guild of America nominations, six American Comedy Awards nominations, three Golden Globe nominations, three Satellite Awards nominations and a GLAAD Award nomination.
