Many advertisers have opted out of the coverage, which means networks will offer TV viewers an entire day of retrospective with little or no commercial breaks.
With retrospectives hard to avoid, will the coverage be seen as overkill?
According to The Associated Press, networks are asking themselves the same thing.
Mark Lukasiewicz, executive producer for special projects at NBC News, said it's a question everyone is grappling with. "I don't think anybody has a handle on it. It's a very tough call. The great thing about television is: If you've had enough, you can turn it off."
NBC will air a commemorative concert the night of 9/11, but will run a Dateline NBC special hosted by Tom Brokaw the night before. The network figures viewers may be overdosed on the subject by midday on the 11th, the AP reports.
ABC and CBS, however, are gambling that people will want to see more. Both networks will focus on reactions of how the government responded in the week following 9/11 in primetime specials.
Here is a rundown of network and cable stations' anniversary coverage on Sept. 11, according to USA TODAY:
ABC Coverage of the day's memorial events from 7 a.m. to 5 p.m. ET/4 a.m. to 2 p.m. PT, four hours of primetime (including a minute-by-minute account of the twin towers' collapse in cooperation with USA TODAY) and Nightline. Peter Jennings will moderate a new edition of Answering Children's Questions, which aired last fall.
CBS With 9/11: The Day That Changed America, viewers will get expanded editions of The Early Show and the CBS Evening News, with primetime coverage featuring 60 Minutes contributors and an exclusive interview with President George Bush. The documentary 9/11 will be rebroadcast Sept. 8 at 9 p.m.
NBC: Themed America Remembers, coverage includes a six-hour edition of Today; a town-hall meeting with rescuers, victims' families and survivors; and continuous coverage anchored by Tom Brokaw and Brian Williams.
