Why does it seem like people in the west forget about eastern religions?

I was talking with a white Australian Hindu just the other day. I myself find Buddhism the most practical religion. I think that Eastern religions are more true to their origins and traditions where as Christianity has embraced commercialism and become more of a fashion and a TV program that takes most the attention. Im pretty sure I last heard Buddhism is the fastest growing religion in Australia. You wont see them holding concerts or running tv programs about it though. Dont pay too much attention to what you see on TV.
