Happy 90th Birthday, Mickey Mouse!

Walt Disney liked to say "It was all started by a mouse," and it all started 90 years ago today!

STEAMBOAT WILLIE starring Mickey Mouse made its debut on November 18, 1928, and it's safe to say that from that point on Mickey and Walt changed the entertainment world in ways no one could have dreamed.

I made a quick stop by Disneyland this morning to pick up a birthday button -- they're being passed out today at every Disney park worldwide -- and I brought home a new friend too!

More great Disney news this week: A lost cartoon starring Mickey's predecessor, Oswald the Lucky Rabbit, has been found in Japan!

Happy Birthday, Mickey Mouse!
