MUMBAI: US network CBS has launched a new broadband television network to capture a greater share of the booming internet advertising market.

The network Innertube will offer streaming video of programmes developed specifically for the internet, programmes that serve as companions to existing CBS shows, as well as material from the media group‘s vast library.

The revenue model for Innertube, which is offered as free to viewers, is based on paid advertising. "In every discussion we‘re having with advertisers, the discussion includes interactive possibilities," CBS Digital president Larry Kramer has been quoted in media reports as saying.

Kramer supported the new revenue model, describing CBS‘s recent success offering an advertising-supported webcast of the annual college basketball tournament. Reportedly, the webcast drew 5 million visits, and led to more than 15 million downloads.
