With the conversion to digital in 2009, TV set manufacters will label analog-only tv's.
It'll read, "Notice: This TV has only an 'analog' broadcast tuner so [it] 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 on that date, as required by Federal law. (It should continue to work as before with cable and satellite TV systems, gaming consoles, VCRs, DVD players and similar products.)"
