Whistle (and cheer) while you work: ESPN says World Cup scored big on computers at offices

The World Cup kept plenty of office workers from doing their jobs.

According to ESPN, fourteen percent of Americans surveyed said they or a friend broke work rules to watch the tournament in South Africa.

The cable network Monday cited research by Knowledge Networks' Total Touch that found 77 percent of out-of-home Internet usage during World Cup matches occurred at offices and 50 percent of out-of-home ESPN mobile use was at offices.

Eighteen percent of people said they or a friend wore their favorite team's World Cup jersey to work during the tournament from June 11 to July 11, and 5 percent said they or a friend broke up with a significant other because of the World Cup.
