HBO launched in 1972 and was the first premium cable television network. It broke new ground with sports programming and films. A key turning point was in the 1980s when it began using digital encryption to curb unauthorized viewing. In the late 1980s, HBO merged with Time Warner. Currently, HBO has over 40 million subscribers and produces around 26 shows across genres like drama and comedy. One of HBO's most successful and influential shows was Sex and the City, which premiered in 1998 and helped establish HBO's brand by pushing boundaries with its explicit sexual content.
