Learning with the tv

In my time we had a television and we had one channel to watch and only during the evening. Now we have more than thousand channels and my children don't know better than the television broadcasts 24 hours a day. And now we have something new; we have some learning channels for the children and they can decide how the program will end because it is interactive tv. They have to answer questions and the tv reacts on what the children are doing by changing the script. My kids like this interactive tv so much.
