TEENick was a teen-oriented television programming block that aired on Nickelodeon. The block launched on March 4, 2001 and lasted until February 1, 2009. TEENick aired on Sunday nights from 6-9 p.m. ET/PT and, beginning in 2004, began to also air on Saturday nights from 8-10 p.m. ET/PT (replacing the popular SNICK block that started in 1992). It was originally hosted by Nick Cannon, and then by Jason Everhart (aka "J. Boogie").
"TEENick" and " The N" had a programming block called TEENick on The N. It aired on January 16, 2007 and then lasted until May 12, 2007, but then returned on March 1, 2008. The block included shows such as '' All That'', The Amanda Show, Drake & Josh, Ned's Declassified School Survival Guide, Unfabulous, 6Teen, Zoey 101, H2O: Just Add Water, My Life as a Teenage Robot and All Grown Up!. On August 3, 2009, TEENick was dropped from The N again.
The TEENick name was discontinued on February 1, 2009 to give a separation of time between the block's end and the September 28, 2009 launch of TeenNick, the replacement name for "The N", a 24-hour network which had progressed from taking half of the broadcasting day on Noggin from 2002-2009 to eventually becoming its own network at the end of 2007 under the former 1999-2007 (2009 on Dish Network) channel space of Nickelodeon Games and Sports for Kids. Nickelodeon continued to air new episodes of live-action series on Saturday nights like iCarly, Victorious, Big Time Rush, How to Rock, You Gotta See This, Supah Ninjas and Bucket and Skinner's Epic Adventures without any theme branding. In Fall 2012, the final episodes of iCarly and Victorious, new episodes of Big Time Rush, How to Rock and You Gotta See This was branded as part of Nick's newest Saturday block Gotta See Saturdays, which airs Saturday mornings and nights.
