I would like to know the number of cable subscribers in the US.  I
would also like to know (if possible) the breakdown between cable
providers, i.e. which companies have what kind of market share.  I
need references/sources included in the answer.

Hello Cellgirl,

Telecommunications Association, there are 66 million cable subscribers
