When sound arrived, it happened quickly. In 1928 the seven Hollywood majors
silent films and 74 sound films, of which 41 had only
synchronised music and sound effects, 23 were
part talkie and only 10, all from Warner Bros, were
all talkie. Universal and Paramount in particular were still heavily committed
to silent productions.

In 1929 the balance had shifted radically. By now there were 166 all talkie releases, 50 part talkie and 36 with only music and effects. Silent releases had dwindled to only 38
out of a total of 290.
