On the other hand, Bright House here in Florida allows access to all of the basic and expanded SD cable channels AND the HD broadcast channels if you plug your TV directly into the wall.
It just depends on the cable company.
I remember the pre-Comcast days (all the way back to Continental Cablevision), when the cable company was supposedly the first (or among the first) in the country to scramble ALL channels, requiring a cable box for any cable reception at all. Obviously, this was the company's way to make some extra money through cable box rentals. A court decision later overturned that, however, requiring at least basic cable without a box. Now with digital cable here, the "at least basic cable without a box" has been changed into letting customers have a certain number of digital converter boxes for free.
