On this day in 1986, The Disney Channel began broadcasting 24 hours a day. When the network first debuted in 1983, it only aired 18 hours a day (from 7 a.m. to 1 a.m.). In 1997, the network took on a revamped look and dropped the "The" in its name and simply became Disney Channel.
The network, which is based in Burbank, California, is slated to begin broadcasting in High-definition sometime in early 2008.
