In 1948, William Boyd made a large bet on television, and on demographics. He had an idea that the first wave of the baby boomers -- kids born to newly affluent parents -- would be a large and untapped audience for the 66 "Hopalong Cassidy" movie westerns he'd starred in, so he bought the rights and sold them to TV stations that were starved for programming. He also made deals with dozens of consumer goods companies to market authorized Hopalong Cassidy merchandise, from wallpaper to cookies to roller skates with spurs on them, and America's kids snapped them up, and Boyd made millions.
