A tipster points out to me that it’s not eBay Inc., the San Jose-based online auction company, one of the most brilliant businesses ever created on the information superhighway. Instead, it’s Houston-based Internet REIT. The giant domain speculator, backed by private-equity investors such as Maveron LLC, which was co-founded by Starbucks Chairman Howard Schultz, has owned the domain name for at least 10 months, according to DomainTools.com. It’s among thousands of domains Internet REIT has acquired that are variations of famous trademarks. A visit to eBayInc.com shows that the domain is parked with advertising broker Oversee.net. Among the marketers whose ads appear on the site is none other than eBay itself.
