Ok, that might be untrue in the sense that you interact directly with the TV (there are a few limited examples of this but none of any import) but many people, especially Gen Y and younger, are spending plenty of time interacting with their TV via the internet.
“Grunwald surveyed 1,277 kids and young adults between 9 and 17, 1,039 parents, and 250 school districts across the US. 64 percent of those surveyed told the consulting firm that they go online as they watch TV, and almost three-quarters of that group (73 percent) said they considered themselves to be actively multitasking when they’re watching TV and using the ‘Net at the same time. 42 percent reported that their attention is split between the TV and Internet equally, while another 47 percent said that once they start using the computer, the Internet becomes the focus of their attention. ”
I’m not surprised that so many kids multitask but it is interesting to ponder the potential for such behavior from a marketing and entertainment angle. What can be done beyond polls and contests and RT-chat?
