Princo is less popular now because they no longer make a lot of media with their brand or MID code, because Pioneer and Philips are trying to sue the hell out of them not paying royalties. You could say Princo is going "underground" now... but this is mostly for their DVD+R media. I can still find Princo DVD-R discs in Canada, but only from very shadey (or stupid) suppliers.
