Excerpt from a “social TV” overview
Instead of fading away as millions of people switch from channel surfing to Web browsing, watching TV is as popular as ever. Americans spend about 4 1/2 hours a day in front of the tube, according to Nielsen Co.
The difference is that we tend to be logged onto the Internet at the same time, often holding a second screen - a device like a smartphone or tablet computer - as we peer at the big set on the wall. We connect to social networks like Twitter and Facebook to chat with friends and family members about our favorite shows, or even the most amusing commercials.
