My main problem with banner ads, even those on TBN, is they're not actually part of the site you're visiting. The site/page you are visiting is made with a hole in it, and that hole is contracted out to a third party advertising host (in TBN's case, a company called doubleclick). That third party advertising host does nothing more than take advertisements created by whomever is willing to pay, and cycles their ad in the holes they're contracted to fill in various sites... This is a wide spread practice and leaves your security while visiting a page to be nothing more than trusting the 3rd party advertising contractors and whomever built the ads you are seeing (most times antivirus is useless in such situations as well, estimated 29-34% detection rate according to the latest research). It's been less than a year since a couple hundred thousand computers became infected within a couple hours by simply visiting NBC.com, all they did was load the page and a bad ad cycled through and infected their PCs... I keep all advertisers and ads blocked and any site that makes ads a requirement, I will no longer visit...
