Looks like big changes are on the horizon today for domain parking. In the past, you had to sign up with a parking company to park your domain. The parking company would use feeds from Google or Yahoo! to serve ads. Now you can bypass the parking companies altogether and go directly to Google: Inside AdSense: Extending AdSense for domains to all publishers Theoretically, this should result in more parking profits, as you are cutting out a middleman. I would expect Yahoo! to follow suit in the near future! I would also worry that at the beginning Google pays well to put the parking companies out of business. Later on, once the parking companies are gone, Google cuts payout dramatically.
