Have you ever imagined life without TV? Personally, I think that this device wreaks unbelievable havoc in a social fabric. I live without television channels for long time and there is nothing I lack.
Try to consider what leads investors to finance projects which have so many flaws that should be legally prohibited, such as TV stations? Answer: the possibility to land the only resource that is unique - human attention. For the "content" presented on TV we always have to pay - our attention.
If we have the resource limited in such a way, it means that we can't devote time to other purposes - our loved ones, parents, children, relatives. We can't sacrifice for the other activities - reading, writing, chopping wood, digging the garden, learning new things, going for walks, cooking, etc. Is called opportunity cost. Indeed, the cost is enormous, because human attention is indivisible, at least for men :)
