Online Advertising: Not done innovating

Give credit to advertisers for always adapting to "what's next." Something as basic as an online banner ad was Earth shattering in the early 90s. Google Ad sense now allows any operator of any Web site to earn some extra change for free (just don't plan on retiring off it!).

Now, something called Ad Networks are changing the online advertising scene for the umpteenth time. An Ad Network operates as a liason between a Web site selling ad space and an agency looking to place an ad. But instead of the agency placing an ad smack dab in the middle of the home page of a site, an Ad Network will place an ad all over the sites less frequented pages as well as smaller Web sites.

It's like hunting with a shotgun instead of a rifle. The Ad Nework buys up ample amounts of ad space on the cheap since the pages with less views have less eyeballs looking at ads. But they then bundle a bunch of these sites together to increase the reach of an ad all over the Web.

This method intrigues me because I don't see it being a "decent way" to go about advertising. It's going to be one of the extremes, either becoming hugely popular or it will fade away before generating any noteworthy results.
