Well another big player is ready to jump into the contextual ad market. Ebay just announced the news at the eBay Developers Conference 2006 which is happening right now in Las Vegas. Donna Bogatin blogs about it at ZDNet.

eBay vs. Google: eBay AdContext contextual ad network set to launch
“One major difference between Google’s AdSense and the new eBay AdContext, is that eBay will apparently be disclosing its revenue share payout schedule with its publisher network partners: Web site affiliates will reportedly receive a cut of 35 percent to 60 percent of sales, depending on volumes.”

Donna also did a story about how eBay and Google seem to be trying to outdo each other. Google announces the GBuy online payment system which competes with eBay’s Paypal. Then eBay comes out with its own contextual ad network to compete with Adsense. There’s lots of ad revenue and market share at stake. Wonder who will win in the end? Google and eBay take each other on.
