How It Works
It was launched in the United States and Japan in the mid-1990s, and is now being deployed throughout Europe. It is available in Canada, France, Germany, Spain, the UK, Austria, Switzerland, the Netherlands, Belgium, and Italy.
The updated programme listings are provided to users free-of-charge, regardless of whether they receive their television signal from an over-the-air (OTA) broadcast or via cable TV or Satellite TV. The service is supported by advertising.
The original analog TV service uses the vertical blanking interval (VBI) of host television stations that datacast the service, similar to the way closed captioning and teletext are broadcast. This can take 24 hours to download on initial setup because the information is sent at a low bitrate.

Famous quotes containing the word works:
“You are always looking for already-felt emotions, just as you like to get an old pair of trousers back from the cleaners, which seem new when you don’t look too closely. Artists are cleaners, don’t let yourself be taken in by them. True modern works of art are made not by artists but quite simply by men.”
—Francis Picabia (1878–1953)
