One you can’t say about CBS is that that their mobile division only phoned it in when it came to working with a mobile ad company. Yesterday CBS Mobile announced partnerships – that’s plural as in multiple deals – with mobile ad companies AdMob, Millennial Media, Rhythm NewMedia and Third Screen Media in efforts to build a one-stop mobile advertising platform for its mobile entertainment, news and sports content.

For CBS this essentially covers all the mobile bases as the four companies offer different ad-serving and distribution technologies and services. With this deal CBS has said it will offer a range of mobile advertising options, including ads on mobile Web sites and commercials in videos.
