CBS completes CNet purchase

CBS Corp., the U.S. broadcaster controlled by Sumner Redstone, completed its $1.8-billion acquisition of CNet Networks Inc., becoming one of the 10 largest website companies.

CNet, along with existing Internet businesses, will form a new digital division led by Quincy Smith, New York-based CBS said. Chief Executive Leslie Moonves sought CNet, owner of GameSpot.com and TV.com, to add Web businesses that are growing faster than the company’s television and radio networks.
