Wrong again. 1080p was/is one of the original 18 formats specified in the ATSC format specification back in 1995. This is the list of the 18 digital TV formats (includes both HD and SD) proposed by ATSC and adopted by the FCC at the
n end of 1996:
1080p 1080 1920 16:9 Progressive 24
1080p 1080 1920 16:9 Progressive 30

Since the TV Morfiend bought was meant for the North American market, the ATSC standard is what applies (US, Canada and Mexico all use it) and it's not relevant to us if the ITU has a different standard.
Edit: here's a copy of the ATSC format spec from 1995:
