Joe,
I am not sure about this being a law here, but I don't think it is yet. But the last time I was in looking at TV sets they had signs telling which TVs would need the converter box and which ones had it built in. I think they had just gotten in a new bunch that had it built in and they had the TVs in three groups. The regular analog type, the ones that were Hi Def ready, and the newer ones that had the Hi Def built in. In any case if anyone isn't sure, they should ask one of the people working in the stores electronics department if they are the newer ones or not, if they don't have the signs telling which is which.
