Used to be that there were only 2 options for TV. You could use the bunny ears antennae or you could pay for cable TV service. Many markets now have multiple choices for pay TV. I could get cable from Comcat, fiber from the phone company or satellite service from DISH or DirectTV. Since the Satellite companies came around they have steadily eaten into the market of the cable companies. The phone companies have also gradually been gaining customers. Today the cable companies are holding onto a slim majority of the market.
I found the data from this 2011 article by the Consumer Electronics Association. Their data is from 2010 but this is the latest source that I could find with the breakdown.
Cable means a traditional cable TV service which has a copper wire that comes to your home. Satellite is either DISH or DirectTV service via the small satellite dish on your roof. Fiber service is the fiberoptic service from a telephone company like Verizon or AT&T. The figure for antenna is the houses that only have antenna.
My father and uncle are in that small minority since they don't watch much TV and/or they are both cheapskates. As far as I can think, everyone else I know has some form of pay TV service. One of my friends only has cable TV because having the 'basic' service makes his internet service via Comcast cheaper or maybe it was that he got the cheap TV package essentially for free if he had Internet with them.
If you do the math you'll find that those numbers add up to 103%. Thats because apparently a few households have multiple pay TV services. I would guess some of the people with more than one pay service do so to get programming only available on certain providers. Other people may have unusual circumstances that warrant more than one pay service, like for example they may have signed up for minimum cable TV service just to get a good price on internet via cable plus satellite service for their television. But thats just guesswork, I don't really know why people would have multiple services.
The CEA report also has data going back year by year from 2005 to 2010. Whats interesting to see is how the market has changed in just 5 years.
The telephone companies have grabbed 10% in just a few years. Satellite has gained almost as much. Cable has lost a similar chunk of the market. Interestingly fewer people in '10 had antenna only service compared to '05. My suspicion may be that was partially due to the digital transition that happened which made some peoples old non-digital TVs obsolete and might have spurred them into getting a pay service. But thats just a guess.
