I can understand why people think that connected TVs will be ‘huge’ because there are so many of them in the world… unfortunately I am not 100% convinced anyone is doing it right. What you need to look at is the behavior of people watching TV. Its different from people on mobiles and they are both different from people on tablets. Companies need to look at behaviors and then work out what those people would find value in. TVs are not personal media devices.
Facebook for example will not work on a TV. TV remotes are fought over by siblings and parents, and something as personal as Facebook will never work on a device that is not personal. Personal media devices are tablets and mobiles. TVs are not personal.
And that is a big difference when you want to do something that works. Sometimes I think that the most money we (Tigerspike) can save for our clients is by telling them not to do things!
