Mickey Mouse (in Portuguese: Mickey Mouse or Mickey Mouse) is a cartoon character (in Brazil, cartoon) and that became the symbol of The Walt Disney Company. The character was created in 1928 by Walt Disney and Ub Iwerks designer   and voiced by Walt Disney. The Walt Disney Company celebrates his birthday on November 18, 1928, which is the release date of Steamboat Willie , although until the mid 1980s the date was celebrated on September 28 . The anthropomorphic mouse has evolved from being simply a character in animated cartoons and comic strips to become one of the best known symbols of the world. One curiosity is that Mickey Mouse would be in the public domain since 1998 - the copyright protection in the United States only lasts seventy - were it not for the approval by Congress of an extension of copyright law (law that it earned the nickname Law Mickey)  which expanded by 20 years the copyright on all American films that had not yet fallen into the public domain, which makes this situation only occurs on November 18, 2018.
