A webpage that could update itself with the latest news, weather, anything really. But it was just a glorified META REFRESH, lets be honest. You needed a 24/7 connection for it to be any use.
Some tended not to like it as it broke the interactive (choose-where-you-go) philosophy of the Internet. But then sometimes it's nice to sit down and be delivered. TV is a good example. Mailing lists kinda is another.
