    Actually, interlaced video in NTSC signal was because the NTSC signal was what we used on old school televisions. An old school televisions used an interlaced scan to display the images. Displayed half the image in one scan and then another display the other one and it displayed both of them so fast it appeared to be one image. That’s why TV screens flicker.

        Not exactly. It’s true that interlaced signals are good at low bandwidth, but the televisions themselves had an interlaced scan picture, so that’s the main reason why NTSC is broadcast interlaced. For the televisions themselves. When we moved away from analog video to digital video, even television signals in the United States began to transition to a progressive scan, especially when we moved to HD and HDTVs
