NBC joins ABC, CNN, MSNBC and E! Entertainment in offering the ceremony live. It's set for 10 a.m. PDT at Los Angeles' Staples Center.
NBC had initially planned only a one-hour prime-time special on Tuesday night, but said Sunday it would also cover the event live. It was not immediately clear who would anchor.
Charles Gibson will anchor coverage for ABC, which is setting aside its typical daytime programming.
CBS anchor Katie Couric will be at the Staples Center, although the network had not yet said whether it was offering live coverage of the memorial.
CNN has seen its ratings soar with the Jackson story, and it will show the memorial on the main network and HLN (formerly Headline News). CNN International will air the ceremony to the rest of the world. Anderson Cooper, Larry King and Don Lemon are the anchors for CNN coverage. Robin Meade, A.J. Hammer and Jane Velez-Mitchell will anchor at HLN. CNN en Espanol also will cover it.
Chris Jansing will anchor live coverage of the memorial on MSNBC. Shepard Smith will anchor live coverage of the ceremony on Fox News, with Megyn Kelly anchoring coverage of the event on the Fox network.
E! Entertainment and TV Guide will cover the ceremony on their television networks and Web sites.
