NEW YORK (AP) — The Summer Olympics opening ceremony takes place Friday, but the first of 5,535 hours that NBC is showing of the games began today with qualifying rounds in women’s soccer. With so many different options, viewers need a road map to make sense of it all.

NBC is promising that every competition in London will be available to U.S. consumers live, with the bulk of them seen online.

The centerpiece of coverage will be NBC’s prime-time, 8 p.m. to midnight on most evenings, with Bob Costas as host. Given the time difference with England, all of the events will be shown on a tape-delayed basis, although particularly rabid fans will have the opportunity to see each of these events online during the day.
