Please help me understand cable technology. Why is it that my cable company can deliver hundreds of high quality TV channels but not an internet service that seems just as fast?

I can't get my head around the following observations:
1) Cable TV delivers hundreds of channels, including dozens in HD, with almost no hiccups. I even get live video broadcasts in very good quality. And while things have been getting better over time, it seems like cable has been "streaming" video to me for decades.
2) The same cable also provides my internet access. Only in the last couple years have websites like Netflix and Hulu been able to deliver something that can sorta compete with the video I get through cable TV. And live broadcasts via the internet are pathetic compared to what I can get on my TV.
Please help me understand what is going on here. I'm not sure exactly how to phrase my question, so I'll just throw out a few...
How is the capacity of the cable infrastructure divided between television and internet services?
Is there something fundamentally different about the data coming to me via the TV service versus the internet service?
If a cable company were to eliminate its TV offering, could it offer me dramatically faster internet service using the existing equipment/infrastructure?
