Originally hosted by Walt Disney himself, the series presented animated cartoons and other material (some original, some pre-existing) from the studio library. The show even featured one-hour edits of such then-recent Disney films as Alice in Wonderland, and in other cases, telecasts of complete Disney films split into two or more one-hour episodes. Other studios feared television would cut into their revenue streams. However, Disney embraced television wholeheartedly, and Disneyland became the first successful TV production created by a movie studio. After its success, Metro Goldwyn Mayer, 20th Century Fox and Warner Bros. produced their own anthology series to promote their respective studios, but none of them lasted very long.
