Here’s something that comes under the category of “things I already believed was true but it is good to have numbers to back up that belief” from NPD:
NPD obtained completed surveys from 10,356 people 13 or older and found that 16% (a bit less than 1 out of 6 people) are using something other than a home computer to download entertainment content from the web. Naturally, iPhone and iPod touch owners led the way. 75% of that device owning group got their entertainment content online. Compare this to the 19% of game console users (presumably both stationary and portable) and 17% of Blu-ray disc player owners. Quite frankly, I’m surprised the Blu-ray percentage is so high since most players are not near an Ethernet jack and may not have a WiFi feature or option.
