01Sound arrives, 1928–1929
The story usually starts with Steamboat Willie in late 1928 and the shock of a drawn character keeping perfect time with a soundtrack. What is easy to forget is how fast the studio then had to work. Through 1929 it turned out Mickey shorts at close to one a month, and the films of that year read as a run of experiments: how to build a gag around music, how much personality a rubber-hose body could carry, how to reuse a good idea without the audience noticing.
02The Silly Symphonies and colour
Alongside Mickey, the studio launched the Silly Symphonies in 1929 — a series with no fixed star, built to let the animators try things. It was here that Disney committed to full three-strip Technicolor in the early 1930s, and here that the discipline of character animation was worked out in public, one short at a time.
03Donald, Goofy and the war
As Mickey softened into a mascot, the comic weight shifted to Donald Duck and Goofy, whose shorts could be faster and meaner. When the United States entered the Second World War, the same crews were turned to propaganda and instructional films — Donald paying his taxes, learning air-raid drill, doing his bit — and the results are among the strangest and most revealing cartoons the studio ever released.
Questions people ask
- When did Disney shorts switch to colour?

- Why did Disney make wartime cartoons?
- After the United States entered the Second World War, the studio produced propaganda and training films for the government and the war effort, repurposing its stars — Donald Duck especially — for morale and instruction.
