In the post-World War II years after 1945, unparalleled economic growth fueled a building boom and a massive migration from the central cities to the new suburban areas. The suburbs were far more dependent on the automobile, signaling the shift from primary dependence on public transportation to private cars. Soon this led to the construction of better highways and freeways and the decline and even loss of public transportation. With all of these changes came a __________ of leisure. As more people owned their own homes, with more space inside and lovely yards outside, their recreation and leisure time was increasingly centered around the home or, at most, the neighborhood. One major activity of this home-based leisure was watching television. No longer did one have to ride the trolly to the theater to watch a movie; similar entertainment was available for free and more conveniently from television.
