Noggin

1999–2009 (TV channel), 2015–2019 (app)
Noggin was originally launched on February 2, 1999 as a joint-venture between Nickelodeon and Children's Television Workshop. The logo was created by Big Blue Dot; just like its sister channel Nickelodeon, it could take many shapes and colors. The logo left the wordmark in Futura Bold. The bottom half consisted of a face, while the upper half could be replaced by various images. When it was launched, Noggin was mostly a channel for pre-teens until 2002, when it was changed to aim at preschoolers. In 2009, it was replaced by the Nick Jr. channel. On February 25, 2015, Viacom announced it would revive the Noggin name as a mobile subscription service aimed at preschoolers set to launch on March 5, 2015.
