ELI5: Why is it 1366x768 that became such a common laptop screen resolution?

Is there any particular reason?

1024x768 was a standard resolution for square aspect ratio monitors, so the 768 presumably comes from keeping that consistent and easily manufacturable.

The 1366 is just brought about from the aspect ratio of widescreen 16:9. Since DVDs were often widescreen it became a standard choice. There was a phase of 16:10 monitors for computers, mine for instance is 1680x1050, but mass production wins out and the decision to use the same resolution across TVs, laptops and monitors drove the price down. That in turn meant other designers went with the lower cost screen...becoming standard.
