I think I was vaguely aware that Marchex had a domain parking service. Apparently it was started in 2006 but has been languishing lately. As of May 1 the doors will close. If you have domains parked there you should move them ASAP.
Marchex made news back in 2004 when it went public as one of the first domain-based Internet companies. The company made some historic domain name purchases, and Yahoo Finance describes them as a “digital call advertising and small business marketing company” and claims that their business earns money from
200,000 of its owned and operated Web sites, and other sources. The company also delivers pay-per-click advertisements to online users in response to their keyword search queries or on pages they visit on its distribution network of search engines, shopping engines, third party vertical and local Web sites, mobile distribution, and its proprietary Web site traffic sources.
