In the beginning, with many amateur filmmakers using whatever kind of video equipment they could find, this was not really a big deal. When Youtube and other video sharing sites were first being implemented, this was the maximum resolution they supported. Eventually, by the time of DVD, NTSC and PAL video would be able to display 720/704 horizontal dots, and the 4:3 aspect ratio would constrain the visible pixels to fit within the frame. The horizontal resolution with analog broadcast or recording equipment (tape) could be anywhere from 300-600 color dots per line.

Normal TVs output a standard resolution : a 525/480 (output/visible) line resolution interlaced at 29.97Hz for NTSC and a 625/576 line resolution at 25Hz for PAL.
