A decent overview of the TV navigation and video search sector, and look at companies like AOL, Google, Gemstar-TV Guide, Hillcrest Labs and MeeVee. Hillcrest is an interesting company: Hillcrest’s content navigation system necessitates the use of a round, ring-like remote with only two buttons and a scroll wheel to zoom in and out of content options. It operates like a mouse and allows viewers to navigate through a visual interface. The service, like Amazon.com, can suggest or recommend content.

Meanwhile, Gemstar-TV Guide will release a new version of its guide in the middle of this year in a phased rollout to Comcast homes. This new iteration will include integrated search capabilities.
