Watching TV while surfing the Internet? You're not alone from Ars Technica

Americans are notorious multitaskers in the workplace, but the latest report out of Nielsen (PDF) shows that we're increasingly multitasking when it comes to media consumption as well. The amount of time spent watching TV (live or time-shifted), watching video on the Internet, using a mobile phone, and even watching video on a mobile phone has all increased. And, because days are (unfortunately) not elastic, the firm attributes this increase across all mediums to people doing more and more at the same time.

According to Nielsen's data, the number of those watching video on their mobile devices increased 70 percent year-over-year, while those who already watched video on the Internet increased their viewing by 46 percent. TV consumption is once again at an all-time high, at 141 hours per month, compared to 139 hours per month during the same period a year ago. Internet use stayed almost completely stable at an average of about 26 hours per month.
