NEW YORK (AP) — Comcast's profit rose 12 percent in the July-September quarter thanks to the Olympics and the first third-quarter gains in video subscribers in a decade. The cable giant has been winning back video subscribers despite an overall drop in the number of people who pay for traditional TV. There has also been a trend toward smaller audiences, even for big sporting events like NFL football and the Olympics. Analysts also say it has been winning customers from some competitors like Dish and AT&T's U-verse TV service, since the telecom giant is now focused on DirecTV instead.
