JPEG will never die. Too many things support it at a very basic level. A random CCD camera module on DigiKey probably has an option for direct JPEG output. An 8-bit Arduino will know how to take that JPEG and display it on a cheap 4" LCD screen off Bang Good.
Formats that sprawl everywhere like that will never, ever die.
