Cartoon Network HD

2007–2010
Cartoon Network launched its HD simulcast feed under the name "Cartoon Network HD".

2010–2013, 2015-present
Beginning the week of May 6, 2013, Cartoon Network removed the HD symbol from its screen-bug. A couple of weeks later, they discontinued the 4:3 feed and began letterboxing the HD feed for SD viewers. Programming originally produced in 4:3, however, remains stretched to 16:9.

On January 2015, Cartoon Network brought back the SD feed for SD viewers, and began to revive the HD symbol on its screen-bug, this marks the return of the SD feed of the network.
