For most of the twentieth-century viewers, the only ways to watch television were through over-the-air broadcasts and cable signals. With broadcast TV, an antenna picks up radio waves to transmit pictures and sound to your television set. With cable TV, wires connect to a set-top box or to your TV itself. These wires run from your house to the nearest cable TV station, which acts as one big antenna.
New technology has changed the way we receive news and entertainment, Radio challenged newspapers in the early 1900s, and television challenged radio. Now, it looks as though traditional television has its own competitor, it's what we're now calling Internet TV.. Medianet is busy with web tv productions too.
