A software application, which presents aggregated content including broadcast, Internet, and local media on a single HDTV display screen. For the most part, this information is pulled from existing databases and supplied by means of an entertainment portal, and then synchronized, resized, and displayed on a single HDTV display screen. This allows mixed entertainment content from creators, broadcasters, advertisers, manufactures, websites, and home consumers to be viewed on a single HDTV display screen, thereby creating a single-screen home entertainment experience. In operation, the screen is divided into multiple areas 200, 202 where web content, which can be continuously updated, is displayed at the same time live video is being aired. This can include any and all types of content; such as news, stock quotes, weather forecast, sports scores, on-line shopping, on-line multi-player games, local community information, etc.

A local community is provided access to a network served by strands of fiber that are routed in a common ribbon or cable sheath. The strands are cut, however, so that there is not a continuous optical path along a fiber strand from the beginning to the end of the cable. Instead, the cut ends of the fiber are each routed to separate customer premises. In this manner, a single cable or ribbon of fiber strands reaches twice as many customer premises. Network access is provided to customers by connecting access equipment, such as switching equipment, to the beginning and ending sides of the fiber ribbon or cable, so that network access is provided to both sides of the cut fiber strands.
