The '90s Are All That is a programming block that airs nightly on TeenNick. The block shows reruns of classic 1990s children's programming, mostly shows that aired on Nickelodeon during their original runs. The block airs in a two-hour block running every night from midnight to 2am, also airing in an encore from 2-4am. The block derives its name and logo from All That, a popular sketch comedy series that ran on Nickelodeon from 1994 to 2005.
The creation of the block, which debuted the night of July 25, 2011 (early July 26), was inspired by a large amount of interest in classic Nickelodeon series from the 1990s by users of social media outlets such as Facebook. From October 7, 2011 through October 23, 2011, the block aired in an earlier time slot, from 10 p.m. to midnight. Response to the debut was very positive; hash tags pertaining to the block became trending topics on Twitter and the Nielsen Ratings for TeenNick on the debut night increased to between eight and 60 times the ratings TeenNick received in previous weeks, beating numerous higher-profile basic cable programs in the same time slot.
Some of the animated programming that has been included in the block was, at the time of the block's launch, already airing in overnight marathons on sister network Nicktoons, a practice that began in spring 2010. The Nicktoons marathons existed simultaneously with The '90s Are All That through August 2011 but have since been removed from the schedule.
