Overview
Tremendous change occurred during the first two decades of the 20th century. By 1910, about 26 million Americans attended movies weekly-a form of popular entertainment that didn't even exist five years earlier. Cars were a rare novelty at the beginning of the century, but by 1916 nearly a half million Model Ts had been sold. In the years surrounding World War I, women finally won the right to vote, and more than a half million blacks migrated from the South to the North.
