Given the hoopla surrounding Jay Leno over the past 24 hours or so, it's easy to forget that the rest of NBC's late-night lineup is getting a makeover, too.

Jimmy Fallon hopes you won't forget about him. The former "Saturday Night Live" regular is taking over "Late Night" in March, and he launched a daily video blog this week to keep viewers informed about what to expect from his version of the show. The first installment revealed the identity of his house band: hip-hop group The Roots.

The band, led by drummer Ahmir "?uestlove" Thompson and MC Tariq "Black Thought" Trotter, will provide the soundtrack for Fallon's show when it debuts March 2. Fallon also informed viewers that his show will originate from Studio 6B at Rockefeller Center, across the hall from where Conan O'Brien currently tapes "Late Night."

The studio carries a good deal of history with it. It housed "The Tonight Show" with hosts Jack Paar and Johnny Carson before Carson moved the show to California in 1972 and dates back to the network's radio days.

It most recently was home to the local newscast for the network's New York affiliate, WNBC.

"We are really excited to be working with Jimmy on the new 'Late Night,'" Thompson says in a statement. "It's also an honor to be working with an icon like ('Late Night' executive producer) Lorne Michaels. We are looking forward to becoming part of the history of 30 Rock."

Fallon will be posting new entries most days at 12:30 a.m. at LateNightwithJimmyFallon.com. (Zap2It.com)

Soon, Wolf Blitzer can sleep in Sunday mornings.

CNN's "Late Edition" is about to get a makeover, with John King taking over from Blitzer, the Sunday newscast's anchor for 10 years.

The first hour of the four-hour block will focus on politics, followed by national and world affairs, the network says.

It also will include "Reliable Sources," the media-oriented discussion program hosted by Howard Kurtz.

With the broadcast's January debut, King will retain his title as chief national correspondent.

Blitzer, CNN's lead anchor for political coverage, will continue anchoring the three-hour "Situation Room" each weekday. Both he and King have extended their contracts through 2012.
