Actually I've been noticeing alot of commercials that are for websites.
Some big companies and some localy branded websites.
For example; I live in Mid-Missouri and I've seen a commercial for FindItCoMo.com latley, it got me to go to the site and I'm getting ready to list a piece of furniture for sale, localy.
And it seems that no matter what the product is that's being advertised there is almost always a website domain name listed somewhere in the commercial.
