Jpeg2000 was a dud because of licensing and patents, not having a year in the name.

  ...and performance (or lack thereof) --- AFAIK the baseline J2K was always implementable freely (similar to the situation with JPEG; arithmetic compression was specified but largely unimplemented due to patents, while baseline JPEG was supposed to be free), but the abysmal performance relative to JPEG for a minor increase in compression efficiency, along with the surprising amount of complexity in the spec, made it a poor choice. There are lots of scanned ebooks on archive.org that use J2K compression, and the sluggishness when turning pages is extremely noticeable compared to others which use normal JPEG.
