DVD’s were still new during that time period. Now if I remember correctly, the DVD was technically invented in 1995. But most countries didn’t have them. Mainly because, the cost of DVD’s were expensive and other platforms like VHS or LaserDisc were also still available and people had already adjusted to them. Plus they were still making improvements to make them more versatile. Anyway, the worldwide release for the DVD in 2000 was the right move considering the year 2000 was a new millennium. The new era of technology.
