A sizable footprint already

Today CBS is expected to announce the addition of Yahoo to CBS Audience Network. The deal would enable Yahoo to syndicate CBS shows on Yahoo TV, alongside existing offerings from NBC and Fox. Ads will likely be pre-rolls, and revenue is expected to be split between CBS and Yahoo.

CBS recently closed a deal to syndicate Heavy.com's The Burly Sports Show on CBSSports.com. The show attracts 2 million monthly visitors.

Advertisers may buy ad space via Heavy's Husky Network ad platform; CBS will manage ad sales for the syndicated version on its site.

In the realm of fantasy sports, CBS also launched CBSSports Fantasy News, a subdivision of CBSSports.com. The site will cover a wide range of sports at no cost. Content includes columns, blogs and other targeted coverage that rival existing subscription-based services.

CBS has been aggressive about improving its digital footprint. Last month, it quietly acquired online news site CNET. At the EconAds Seminar in New York, President Jo Ann Ross discussed the pending transaction called CNET a complement to CBS' current offerings.

It will also grant CBS access to young, tech-savvy men.
