Korea’s GDP per capita in 1950 was similar to that of Bangladesh around the same time: https://www.nationmaster.com/country-info/stats/Economy/GDP-.... In the alternate timeline where there isn’t a capitalist south korea, the Korean peninsula has 100 million+ people living in poverty and squalor, like Bangladesh today. The cost of that is tens of millions of lost lives resulting from higher infant and child mortality rates.

Let's say that back in 1930s when they were assigning frequencies for the broadcast television channels, they allocated enough extra bandwidth for a future color (chroma) signal, apart from the existing monochrome (luma) signal.

If the bandwidth was available, would it have been possible to include separate chroma and luma components in the broadcast signal without the two interfering with each other, thereby producing a much cleaner color image while maintaining backward compatibility with the original B&W TV sets?

If you watch footage of the Apollo 17 LEM liftoff from the moon, you can see color artifacts in the burst of fragments off the platform. Their motion is too fast to stay in the same color band.
