The largest television network in America is not ABC, CBS, or Fox．Nor is it one of the cable net—works such as CNN, which carries only news and news stories．It is not ESPN, the all-sports cable net-work, or even MTV, which is famous for its music videos．Rather it is PBS, Public Broadcasting System, a non-profit public broadcasting TV service．PBS has 349 member television stations in the U．S．and some member stations by cable in Canada．
PBS only attracts a minority of all TV viewers, about 2 percent．The industry leader, NBC, however, attracts 11 percent of viewers．But the growth of public television in the past two decades has been dramatic．This is especially noteworthy when one considers that public television stations must often survive on very limited budgets, on viewers’ donations, and on private foundations and some governmental funding．
