I want to know the answer to the following question:
Most television sets sold since what year have an ATSC tuner?
All the background I'm provided with is that "This is achieved with a TV aerial, just as it has been since the 1940s except now the major network signals are broadcast in high definition (ABC, Fox, and Ion Television broadcast at 720p resolution; CBS, My Network TV, NBC, PBS, and The CW at 1080i).". Is that enough to answer the question?
Answer: no
