Comedian and actor Garry Shandling died unexpectedly yesterday, and tributes to both the man and his work have already begun pouring in. At the center of many of them is The Larry Sanders Show, Shandling’s second scripted series, after It’s Garry Shandling’s Show. Running on HBO from 1992 to 1998, the television show about a television show continued It’s Garry Shandling‘s healthy meta streak while adding a style of humor driven by awkward and not-so-slightly pathetic human failings rather than punchlines. For both its sensibility and its alumni, who went on to be some of today’s most influential figures in both television and comedy, Larry Sanders is a titanic presence in contemporary culture. Here are some of the series it made possible, many of them trailblazers in their own right.
