Is there an on-line resource for TV commercial cast lists?

There is this one actress who has appeared recently in a Burger King ad and a Verizon (or maybe another phone company) ad.

She just strikes me every time I see her. She’s this pretty red head.

Is there a IMDB for tv ads?
I want to find out who she is so I can stalk her… Or …Not.

Well, this probably won’t help in your specific case, but there is an “Other Works” section in the imdb listings, which includes commercials done by TV/movie actors.
