Here in the Texas area, Verizon's FiOS service is easily $80-100 a month. That's for the base internet + tv package, with no special channels, too. That does not include HBO, or any other movie channel. At one house that I lived at for a year or so, we paid $180 a month for TV + internet, no phone line. That was simply because we wanted HBO and some sports channels, and good internet, with like two extra DVR boxes.

I consider $100 on TV + internet to be pretty average, if not lower average.

Edit: deleted message said something about $100 being way more than he had seen for TV and internet bundles.
