  > JPEG2000 had nothing of that... That’s not true. JPEG 200 had substantially smaller file sizes and better progressive decoding – something like responsive images could have just been an attribute telling your browser how many bytes to request for a given resolution. It also had numerous technical benefits for certain types of images - one codec could handle bitonal images more efficiently than GIF, lossless compressed better than TIFF, effortlessly handle colorspaces and bit depths we’re just starting to use on the web, etc. What doomed it was clumsy attempts to extract as much license revenue as possible. The companies behind it assumed adoption was inevitable so everything was expensive - pay thousands for the spec, commercial codecs charged pretty high rates, etc. and everyone was so busy pfaffing around with that that they forgot to work on things like interoperability or performance until the 2010s. Faced with paying money to deal with that, most people didn’t and the market moved on with only a few exceptions like certain medical imaging or archival image applications. In the early 2000s the cost of storage and disk/network bandwidth meant you could maybe try to see the numbers as plausibly break-even but over time that faded while the hassle of dealing with the format did not.
