10. 'The Larry Sanders Show'
If the Larry Sanders Show had come around in the age of Twitter and Facebook, it would have been an instant sensation with blogs devoted to the show and in-depth recaps publishing hours after each new episode aired. But it arrived in 1992 and never became anything more than a huge cult favorite. It stuck around for six seasons and advanced the careers of Janeane Garofalo, Bob Odenkirk, Jeremy Piven and many others, but it truly deserved to be as massively popular as Seinfeld or any other show of the era.
