Asia has long been ahead of the West in video formats, and audio. Most of those formats were made there, so it stands to reason. What is curious is why it took so long to get popular in the West.
What do you mean with "most of those formats were made there"? The only thing I can think of is early digital video camera codecs. Even when these were created, MPEG-1 and H.261 had been around for years.
