CBS Interactive on Monday is expected to launch a multichannel industry ad campaign.

The campaign, titled "Only CBS Interactive," promotes the unit's position as a leader in multiple categories, as well as its position as a Top 10 Web property worldwide.

The campaign builds on the "ONLY CBS" campaign from last spring, which touted CBS as the only network up in every key demo. The new campaign communicates the company's position in offering the best brands the Internet has to offer.

"The 'Only CBS Interactive' campaign communicates our leadership in digital media just as the original 'Only CBS' campaign communicated the company's leadership in network television," said Neil Ashe, president of CBS Interactive.

CBS Interactive's brands include its CNET tech media site; CBSSports.com; its GameSpot gaming information Web site; and CBS.com. Additional CBS Interactive properties include BNET, MoneyWatch, CBSNews.com, TV.com, TheInsider, Last.fm, CHOW and ZDNet.

The ads are running in industry trade publications including AdvertisingAge, MediaBistro, and MediaPost, among others.

The campaign also expands this week with spots running across CBS Interactive sites, including CNET.com, BNET.com, CBS MoneyWatch.com, Last.fm and CBSSports.com.

CBS Interactive is currently the ninth-largest Internet property worldwide, reaching nearly 200 million people a month, according to comScore MediaMetrix.

Its CNET property recently reported 27% growth in unique users; whlie GameSpot increased unique users by 13%, and Last.fm grew unique users 52%. TheInsider.com grew 473%; and Chow grew unique users 45%.
