Felix The Cat is among our oldest cartoon characters, dating back to 1919 and the era of silent films. And he practically invented television. In 1928, in RCA's very first experimental TV broadcast, an image of a papier-mache Felix doll spinning slowly on a phonograph was beamed out of a Brooklyn lab. (On W2XBS, in case you wanted to check your TiVo.) RCA televised Felix on a daily basis for most of the next decade.
Felix got back into TV in 1953, when some of his old films were licensed to television, among the first programming for children. By 1958, he had his own series -- and next week Classic Media is releasing the 31 episodes (in color!) on DVD for the first time. Happy birthday, pal.
