The Huffington Post notes that NBC Nightly News had almost a million more viewers last week than the week before, putting it back on top in the ratings--and attributes the bump, plausibly, to anchor Brian Williams' much-hyped November 3 appearance on Saturday Night Live.

The obvious lesson the networks will draw is that the best way to promote their news anchors to a younger audience is by putting them on shows that young people actually watch. In other words, brace for Charlie Gibson on Dancing with the Stars.
