Heavy usage of one of the top 3 media (by reach) does not necessarily mean that less time is spent with the other media, according to [download page] results from an Edison Research and Arbitron study. The study looks at self-reported average time per day spent with the internet, TV, and radio, sorting the results by heavy users of each. Heavy internet users (4+ hours per day) report spending more than 7 hours per day on the internet – but the amount of time they spend watching TV (3:35 vs. 3:33) and listening to the radio (2:07 vs. 2:04) is on par with the general population.
