Coca-cola who made red Santa Claus popular

When I think about Christmas, the first image comes into my mind is the affable looking about Santa Claus as I regard it as a symbol of Christmas, which is used everywhere especially the shopping malls during Christmas seasons. And this happens in big cities in China, where people don't really celebrate Christmas, as a way to do promotion. For years, I thought his image came from religion. So I was astonished when I knew that the original version of Santa Claus was in green and purple and it was Coca-cola that made the red one also the standard one popular with the mass audience. So I can see part of the Christmas ritual was modified just by years of advertising.
