By 1926, Winkler's role in the distribution of the Alice series had been handed over to her husband, the film producer Charles Mintz, although the relationship between him and Disney was sometimes strained.[48] The series ran until July 1927,[49] by which time Disney had begun to tire of it and wanted to move away from the mixed format to all animation.[48][50] After Mintz requested new material to distribute through Universal Pictures, Disney and Iwerks created Oswald the Lucky Rabbit, a character Disney wanted to be "peppy, alert, saucy and venturesome, keeping him also neat and trim"

The first Oswald cartoon, Poor Papa, was rejected by the Universal studio heads for its poor production quality and the sloppiness and age of Oswald.[13] Disney, together with Iwerks, decided to create a second cartoon titled Trolley Troubles featuring a much younger, neater Oswald. The short, released on September 5, 1927,[12] officially launched the series and proved to be Universal's greatest success to date. Poor Papa was later released in 1928 and the storyline was reused in a Mickey Mouse short five years later, in Mickey's Nightmare, 1932.[13] Oswald the Lucky Rabbit became Universal's first major hit in 1927, rivaling other popular cartoon characters, such as Felix the Cat and Koko the Clown.
Oswald the Lucky Rabbit
The Alice Comedies are a series of animated/live-action shorts created by Walt Disney in the 1920s, in which a live action little girl named Alice (originally played by Virginia Davis) and an animated cat named Julius have adventures in an animated landscape.

In February 1928, Disney hoped to negotiate a larger fee for producing the Oswald series, but found Mintz wanting to reduce the payments. Mintz had also persuaded many of the artists involved to work directly for him, including Harman, Ising, Carman Maxwell and Friz Freleng. Disney also found out that Universal owned the intellectual property rights to Oswald. Mintz threatened to start his own studio and produce the series himself if Disney refused to accept the reductions. Disney declined Mintz's ultimatum and lost most of his animation staff, except Iwerks, who chose to remain with him.
Walt Disney
To replace Oswald, Disney and Iwerks developed Mickey Mouse, possibly inspired by a pet mouse that Disney had adopted while working in his Laugh-O-Gram studio, although the origins of the character are unclear.

Steamboat Willie is a 1928 American animated short film directed by Walt Disney and Ub Iwerks. It was produced in black and white by Walt Disney Studios and was released by Celebrity Productions. The cartoon is considered the debut of Mickey Mouse[2] and his girlfriend Minnie, although both characters appeared several months earlier in a test screening of Plane Crazy. Steamboat Willie was the third of Mickey's films to be produced, but it was the first to be distributed because Walt Disney, having seen The Jazz Singer, had committed himself to produce one of the first fully synchronized sound cartoons.
Steamboat Willie
Steamboat Willie is especially notable for being one of the first cartoons with synchronized sound—the first one was Song Car-tunes by Fleischer Studios in 1924—as well as one the first cartoons to feature a fully post-produced soundtrack, which distinguished it from earlier sound cartoons such as Inkwell Studios' Song Car-Tunes (1924–1927) and Van Beuren Studios' Dinner Time (1928). Disney understood from early on that synchronized sound was the future of film. Steamboat Willie became the most popular cartoon of its day.[3]

By 1934, Disney had become dissatisfied with producing formulaic cartoon shorts,[77] and believed a feature-length cartoon would be more profitable.[78] The studio began the four-year production of Snow White and the Seven Dwarfs, based on the fairy tale.

Snow White and the Seven Dwarfs is a 1937 American animated musical fantasy film produced by Walt Disney Productions and released by RKO Radio Pictures. Based on the 1812 German fairy tale by the Brothers Grimm, it is the first full-length traditionally animated feature film and the first Disney animated feature film. The story was adapted by storyboard artists Dorothy Ann Blank, Richard Creedon, Merrill De Maris, Otto Englander, Earl Hurd, Dick Rickard, Ted Sears and Webb Smith. David Hand was the supervising director, while William Cottrell, Wilfred Jackson, Larry Morey, Perce Pearce, and Ben Sharpsteen directed the film's individual sequences.

Snow White premiered at the Carthay Circle Theatre in Los Angeles, California on December 21, 1937. It was a critical and commercial success and, with international earnings of more than $8 million during its initial release, (compared to its $1.5 million budget), it briefly held the record of highest-grossing sound film at the time.
Snow White and the Seven Dwarfs (1937 film)
For years, Walt Disney worked on the Alice Comedies, a series of animated/live actions shorts of which Disney grew tired, deciding to move away from the mixed format to all animation and crating his overall first cartoon, Oswald the Lucky Rabbit, in 1927. After losing the rights to this character, Disney developed Mickey Mouse as a replacement, which debuted in the animated short Steamboat Willie on November 18th, 1928, notable for being the first cartoon made with synchronized sound. By 1934, Disney had become dissatisfied with producing formulaic cartoon shorts and believed a feature-length cartoon would be more profitable, beginning the four-year production of Snow White and the Seven Dwarfs. The film was Disney's first animated feature film, releasing in 1937 to critical and commercial success.
