If it helps your site, Dave, go for it. My suggestion is don't make any ads animated, its annoying and kitschy, like a porn site. If folks want a demo or a video of the product, they can click the ad link for more details.
On the user end, we can do what we find is best for us too including blocking.
I find web ads helpful as the info and prices about them are current; magazine ads tend to be out of date by the time they go to press. A long time ago, a mag called Computer Shopper was 90% ads and was typically as thick as a phonebook. Most people bought it purely for the ads. Today, its nothing like it was, but that was before the Internet made is useless:
When it comes to purchasing gear or parts, finding price and availability is everything. All things considered, if 2 parts are competitively spec'd but one is cheaper, or one has a discount through eevblog, then often the cheaper one wins.
I still get the Jameco and Digikey paper catalogs because its not easy to scan the website looking for what can do what but I never use it to buy anything.
