I picked up a juicy rumor this weekend that Cisco may have acquired Click.tv, a video annotation and deep tagging service that launched in 2006 and then shut down last month.

When Click.tv closed down last month they said in an email to users “While I regret this shutdown, I am very excited by the reason behind it. You’ll be seeing Click.TV technology very soon doing *much* bigger and better things.” This certainly suggested a complete relaunch or an acquisition.

Was it Cisco? Maybe. They’ve been making some interesting plays in the web space, with acquisitions of Five Across, Tribe and WebEx. Five Across and Tribe are both in the social networking space. I’m not sure how Click.tv would fit into those plans. So for now I’m going to label this as possible but not more. I’m digging for additional sources.
