Jupiter Research said that its upcoming annual report into media consumption will show that the proportion of time spent on the internet compared to other channels has remained the same, in a major change from previous years.
Nate Elliott, associate analyst at Jupiter Research, said that people's interaction with media is increasing in general and that there is room for all different formats.
Elliott said: "The results for 2006 are identical to 2005. There has been no change in consumption. In 2004 and 2005, internet time doubled from the previous year and a large portion of that was down to broadband.
"The notion that media is a zero sum game is a false one. Most people assume that a rise in one medium has to be balanced by a fall in another.
"What happens is that when consumers take up new platforms they are adding to their media time, not spending less time on TV per se."
