The predecessor of Columbia Pictures, Cohn-Brandt-Cohn
Film Sales, was founded in 1919 by Harry Cohn, his brother
Jack Cohn, and Joe Brandt. Brandt was president of CBC
Film Sales, handling sales, marketing and distribution from
New York along with Jack Cohn, while Harry Cohn ran
production in Hollywood. Many of the studio's early
productions were low-budget affairs; the start-up CBC
leased space in a poverty row studio on Hollywood's Gower

Following a reorganization, partner Brandt was bought out,
and Harry Cohn took over as president. In an effort to

Columbia's product line consisted mostly of moderately

Columbia's short-subject department employed many
famous comedians, including Buster Keaton, Charley
Chase, Harry Langdon, Andy Clyde, and Hugh Herbert.

In the early 1930s Columbia distributed Walt Disney's
famous Mickey Mouse cartoons. In 1934 the studio
established its own animation house, under the Screen
Gems brand.

Columbia also produced musical shorts, sports reels, and
travelogues. Its "Screen Snapshots" series, showing
behind-the-scenes footage of Hollywood stars, was a
Columbia perennial; producer-director Ralph Staub kept
this series going through 1958.
