Whether or not you’re convinced that in the age of on-demand there’s an appetite for live TV over the Internet, two services that deliver just that are claiming impressive growth.

“Zattoo is growing nice and steadily”, the company’s UK and Ireland Country Manager, Alexandra Illes, told last100 in an email. “We have reached over 2.4 million [users] and are now available in over eight countries.” Zattoo delivers live streaming of existing ‘over-the-air’ and cable channels, with various channel lineups depending on country.

IIles was writing to tell us about the latest Zattoo software update which adds features including new channel management functionality. “With a channel line-up that’s getting bigger and bigger, we thought it important to allow users to arrange channels in self-defined groups and change the order of the line-up. The idea is that each user can customise the Player to suit their viewing habits.”

In a press release put out on the same day, LiveStation, a similar service to Zattoo that streams a number of television and radio news stations, boasts that their users “have already spent seven years watching live news on their PCs.”

Whatever that means.
