Do you ever think we will be able to buy cable channels directly and watch them streaming on the net and avoid the cable company all together?

We got sick of paying the cable company and got an antenna. We get a lot more channels that I thought we would, but I miss MSNBC, the History Chanel and such.
I know that I can watch some shows on demand from their websites, but I would just like to pay a couple of bucks a month to watch their channels streaming and not pay the cable companies to get the crap I don’t watch anyway.
Is this day coming? Have any of you tech savvy folks been in the loop?
