It's not only YouTube that's notorious for its uploading format, but it's the same standard across other sites too. The main reason is due to it's wide availability of Adobe Flash Player in the major web browsers. Besides that, an FLV video file format is smaller in terms of file size compared to an AVI and hence, would not take up a lot of storage space.
