It almost sounds like you're asking why people watch shows rather than why they record them. I mean, if you're going to watch shows, then you have three options:
*
Do it live.
* Record it and watch it at your leisure.
* Find it On Demand or on the internet.
So obviously, you record it if you want to watch it and you can't watch it live and you can't find it on demand or on the internet. Are you normally able to watch everything live? That seems almost impossible for me but I guess if your life isn't quite as busy you could do it.
Now, why do you watch shows in the first place? I don't know. There aren't many "shows" I watch. Just don't have time any more. I tend to record sports and movies on premium channels that would cost money otherwise. Occasionally I'll record specific episodes or events that I want to watch (like a talk show with a guest that I want to see).
