Frankly I'm surprised the FTC in the US allows that term to be used at all. It's a much bigger stretch than calling a 41.5" display 42"
At least this is something the stores are good about. From what I've observed, they would usually list a TV like that as "42" class," and then list the actual dimensions. I assume they do this to get better yields on the glass?
How long before someone markets their WiFi equipped TV as "Wireless TV" ?
I think they get by just fine on calling them "internet TVs" or something like that."
