"Linking Web content and traditional TV programming into a searchable database for viewing is a smart idea," says
ZDNet's Between The Lines. "What's also interesting is Google's use of the Android OS as the backbone technology for the set-top box ... The operating system has largely been talked about in the form
of netbooks -- but there's no reason that it couldn't power something like a set-top box."
"Potential hurdles could include the necessity of new set-top boxes -- something
households and service providers rarely upgrade -- and service providers' reluctance to share any more information with Google than they already do," notes Business Insider.
Also, "Google will have formidable competition on its hands from the likes of Clicker, a service seeking to identify,
categorize and make discoverable the ocean of video and digital entertainment online and off," writes Search Engine Land's Greg Sterling.
For context, Sterling also references a recent survey of US new TV buyers from iSuppli, which found that 27% of TVs were connected to the internet.
