The owners of the domain adsense.com have been fielding hundreds of customer service e-mails and phone calls regarding Google's AdSense program since the advertising service launched in March 2003.

Unfortunately for the domain registrants, they have no connection with Google, except for the fact that they happen to share the name.

Alexis Garrett, marketing director and co-founder of AdSense Consulting, a Eugene, Oregon-based marketing and design company, registered the URL in 1996. Call the number listed until recently on adsense.com, and she'll likely answer the phone. But she'd rather you didn't, unless you're an actual prospective customer.
