What is a good book about TV and how it has changed us?

I love this book. It makes you want to throw your television out the window. It is amazing the decrease in vocabulary, attention span and more as compared to common people at the time of Abraham Lincoln. TV has made our world a world of entertainment rather than learning. I would love to see this book updated with a study about our current generation with internet and cell phone texting. No doubt things are only getting worse. This is the book that encouraged me to commit to reading classic literature and I have immensely enjoyed many of the books I've read since this book woke me up.
