Cartoon Network

Cartoon Network (often abbreviated as CN) is an American cable television channel owned by Warner Bros. Discovery through its US networks division.

1991 (pre-launch)
Before Cartoon Network started broadcasting on October 1, 1992, this logo was used in its marketing to cable operators and advertisers. The middle of the logo could be edited to feature all the characters (1 at a time) from shows that were planned to be aired on the network. It had many color variations including the text, as shown on some parts of the presentation reel. This logo was designed by J.J. Sedelmaier Productions, who also animated earlier episodes of Beavis and Butt-Head, as well as the pilot/first episode of Harvey Birdman, Attorney at Law.

1992–2004
On October 1, 1992, Cartoon Network was officially launched and debuted its now-iconic logo, featuring a black and white 7x2 square grid with each letters of the company's name on it. Around this time, Cartoon Network launched to only a handful of cable operators. The logo was designed by Corey McPherson Nash under Hatmaker.

2004–2010
On June 14, 2004, Cartoon Network launched a new on-air look, and a new logo replaced the one that had been used since the network launched nearly 12 years earlier. The logo's design was made up of two black and white cubes with the network's initials ("CN", borrowed from the previous logo) written on them, and the network's full name underneath it, also in the same typeface as the previous logo. The development of the network's new on-air identity was led in-house in association with Animal Logic in Sydney, Australia.

2010–present
On May 29, 2010, Cartoon Network introduced an updated logo and on-air look, created by its in-house design team and Brand New School. The new slogan for the network, "CHECK it", was introduced (possibly a play on the design of the network's former "checkerboard" logo). The checkerboard theme is used extensively in the new look. It was first used in bumpers featuring Chewbacca to promote the third-season finale of Star Wars: The Clone Wars. The new logo was later brought to various European countries in November 2010.
