ABC also scored highest on a new Nielsen survey of viewers who turn to the Internet to watch shows they have missed on the air. According to the survey, half go to; 41 percent to NBC; 37 percent to CBS; 24 percent to Fox, 17 percent to YouTube; and 15 percent to iTunes. Still, the number of actual viewers appeared low. Only 25 percent of those surveyed said they had watch an entire episode of a TV show via the Internet during the past three months. Among older viewers (55+) only 11 percent had done so.
