Recently some TV stations have begun broadcasting full strength DTV signals hence leaving older televisions without built-in digital tuner with fewer stations. These stations have stopped broadcasting their digital signals all together. So even if you have cable you may need a DTV Cable Box for each Analog TV in your home becomes a question.

The FCC and the cable companies have left most of their publications open to interpretation by using word like "Should" & "Probably"

As of March 1, 2007, all television receivers shipped in interstate commerce or imported into the United States must contain a digital tuner. In addition, effective May 25, 2007, the Commission required sellers of television receiving equipment that does not include a digital tuner to disclose at the point-of-sale that such devices include only an analog tuner, and therefore will require a digital-to-analog converter box to receive over-the-air broadcast television after the transition date. Retailers must inform consumers by prominently displaying the following text if they are selling TV equipment with only an analog tuner: "This television receiver has only an analog broadcast tuner and will require a converter box after February 17, 2009, to receive over-the-air broadcasts with an antenna because of the Nation’s transition to digital broadcasting".
