We've had all kinds of press for our site, radio, tv, newspaper, etc. We get bigger spikes in traffic being featured on blogs nobody's ever heard of with a link to our site than being featured in national outlets like NPR and LA Times where viewers have to remember to look us up online later. That said, the people who hear about you offline will find you weeks and months later and sometimes make a purchase over a year later. I agree, put a "Welcome Oprah Viewers" banner on your site. Also, you can run an adwords campaign for a few weeks to capture Oprah's viewers. Set up your keywords keeping in mind they're going to be googling phrases like "website selling chocolate chip cookies (or whatever it is you do) as seen on oprah tv."
