BERLIN (Reuters) - The popularity of the women's soccer World Cup is the latest sign of a virtuous cycle in female sport as increasing advertising revenue boosts professionalism and viewers.
Television audiences for the early women's World Cup matches in Canada are up strongly in many countries compared with the last competition in 2011, doubling or tripling in major markets like the United States and China.
Fox Sports, which is airing all 52 games live, is expected to raise ad revenue of more than $30 million, a person familiar with the matter told Reuters.
