Olympics coverage will again air on cable networks MSNBC, CNBC and Bravo this summer.
All three networks are owned by Comcast's NBCUniversal, which will use NBC and NBC Sports Network as the central platforms for the London Games.
News channel MSNBC will broadcast events in up to 20 different sports 9 a.m. to 6 p.m. EST on most weekdays, with longer windows over the weekend. Basketball and soccer will be part of the 155½ hours of programming over 19 days, starting July 25, two days before the opening ceremony.
Lifestyle network Bravo will show 56 hours of tennis from July 28 to Aug. 3. Live matches will air from early morning until mid-afternoon in the Eastern time zone on most days.
Business channel CNBC will televise 73 hours of boxing from July 28 to Aug. 12, including the debut of women's boxing. Taped bouts will be broadcast from 5 p.m. to 8 p.m. EST each weekday, with six hours of live coverage on Saturdays and Sundays.
In Olympics to date, those with the TV rights have elected to delay coverage to primetime broadcasts. Comcast previously announced that it will offer live coverage of events of the 2012 games.
