“Whoa, A Sony format that didn’t bomb!” Yeah, not at all like the CD, DVD+R, Professional Industry Beta and HDCam formats. Mini Disc can be argued either way depending on where you live and what industry you work in. BluRay is still being decided. The only format they really created that failed in any major way was UMD. But most people aren’t aware that Betacam is still used (newer revisions of course) in the TV & Movie production industry.
