Yellowpages.com was founded in 1996 during the dotcom boom, by multiple co-founders, including CEO Dane Madsen.
Yellowpages.com became part of Globalgate, an ecommerce incubator and investment company in 1998, which sold the business to its largest investors in 2001. In late 2004, BellSouth Corp and SBC Communications Inc. purchased www.YellowPages.com Inc. reportedly for US$120M. The companies formed a joint venture to run the business.
The two companies had been working together on another joint venture called Cingular, a wireless carrier in the US. Each company had its own Online Yellow Pages: BellSouth owned RealPages.com and SBC owned SmartPages.com. The two sites effectively merged into the newly acquired YellowPages.com.
