CBS Interactive Games is adding the virtual equivalent of a live sports feed to its GameSpot site. Twitch.tv, which streams competitive multiplayer games around the world, will provide live streams of hugely popular games like DOTA 2, World of Warcraft and Call of Duty to Gamespot's audience base, with CBS selling ads around the new content.
Even without the boost from the GameSpot audience, Twitch has already found sponsorships with brands like energy drink company MiO.
