NTSC
From Tardis Wiki, the free Doctor Who reference
NTSC was a format for recording video that was the standard in the United States, at least as late as the 1990s. When Anji Kapoor bought an American VCR, she unwittingly made it impossible for her to play the tapes her family had sent her from England, because they all used the PAL standard.
