U.S. law phased out Analog-Only tuners in a "TV Set", it had to include ATSC.
If Canadians can still buy Analog-Only "TV Sets", consider yourselves lucky
to have an inexpensive option for use with Analog signals still available OTA
and on Cable/SAT systems. An inexpensive, battery operated "TV Set" is now
a thing of the past in the U.S.
Manufacturers are still allowed to sell "Monitors" which do not have ANY tuners.
Which are less expensive for the vast majority of viewers who subscribe to Cable or SAT.
Or simply want to connect them to a Game Set or DVD Player....or a CECB Converter Box.
This could hardly be called "dumping"....
And for additional cost, you can also buy a Digital Cable Ready (DCR) TV, which has
Analog and Digital QAM capability for Cable....and just because they can....OTA ATSC....
BTW: A "TV Set", by definition, must include some sort of tuner....otherwise it's a Monitor.
