Virginia entrepreneur, Halsey Minor has purchased Carter’s Grove Plantation — an 18th-century mansion built by one of Virginia’s founding families — for $15.3 million from the Colonial Williamsburg Foundation.

The property includes a Georgian-style mansion and 400 acres that are subject to a conservation easement, as well as 76 acres adjoining the property.

The foundation has owned the 35-room, two-story home and land since 1969. Citing financial pressure, the foundation announced plans to close Carter’s Grove to the public in 2002. The home was shut in 2003.

Minor, who was born in Charlottesville in 1964 is a technology entrepreneur who founded CNET in 1993. Minor ran CNET for 8 years during which time it became one of the Internet’s first companies to achieve profitability. The company’s many achievements were recognized in 1999 when CNET was selected as one of only 2 Internet companies to join the elite NASDAQ 100 which included companies such as Intel, Microsoft, Cisco, Home Depot, and Dell.

Minor also developed two other spin-off companies which independent of CNET became public entities: Vignette Software and Snap/NBCi. Minor is currently investing in new companies in a broad range of fields via Minor Ventures.

Minor attended Woodberry Forest School and the University of Virginia, where he was a member of St. Elmo Hall and received a degree in anthropology. After graduation, he worked at Merrill Lynch, before moving on to start his own company.

In the late 1980s, he collaborated briefly with Jeff Bezos, the future founder of Amazon.com on a personalized news business plan. Minor was also the founding and largest investor as well as silent partner in the development of salesforce.com.

In November, Virginia-based bloodstock agent and former VTA president, Debbie Easter purchased Dream Rush for $3.3 million at the FasigTipton sale on behalf of Minor.
