“It’s good to be home,” Leno told his audience last night. “I’m Jay Leno, your host. At least for a while.”

Preliminary Nielsen Co. numbers show Leno’s return scoring a 5.4 rating and a 14 percent share of the viewing audience. In comparison, ABC’s “Nightline” received a 3.4 rating and 8 percent audience share.

But it’s the Leno vs. Letterman ratings battle that matters, and last night didn’t give CBS’ “The Late Show” the best numbers in the world, pulling a 3.0 rating and 8 share.

Of course, everyone wanted to see what Leno would do on his first night back. The trick, of course, is to keep those ratings while building an even larger audience. Only time will tell if Leno still has the ol’ magic.
