Not old at all. Almost every TV sold in the US with an ATSC receiver (so most mid to high end) will also do NTSC (and "clear"/unencrypted QAM-64/256 for cable)

Not old at all. Almost every TV sold in the US with an ATSC receiver (so most mid to high end) will also do NTSC (and "clear"/unencrypted QAM-64/256 for cable) In the past decade it became more common for low cost TVs to drop the tuner entirely. These use jellybean tuner/demod parts and you tend to get the whole batch or nothing at all, once you have RF in, demodding NTSC is basically free.
