CBS to buy CNET Networks for $1.8bn

US broadcast network CBS is buying internet publisher CNET Networks in a deal worth $1.8bn (925m).

CNET began as a technology news service but now owns a string of websites including ZDNet,, and

CBS, which bought the internet radio service last year, said that after the CNET acquisition its websites together would receive 200m unique users a month.

Leslie Moonves, CBS chief executive, said: "There are very few opportunities to acquire a profitable, growing, well-managed internet company like CNET Networks.

"CBS stands for premium content and unparalleled reach, and CNET Networks will add a tremendous platform to extend our complementary entertainment, news, sports, music and information content to a whole new global audience."

The deal has been unanimously approved by CNET's board and will formally be completed later this year.
