The milestones switch from journal articles to corporate press releases at some point. They miss the vibrant and interesting marketplace technology transitions. I can think of several marketplace transitions that were never journal articles nor corporate press releases: The conversion of home/personal sized computers from linear power supplies to switchers. The widespread eventual total conversion of home appliance-type wall warts from transformer based linear supplies to switchers. The conversion of radar from multi-KW pulsed magnetron to multi-watt solid state doppler. "Successful" deployment of multiple trunking-style public safety radio networks. Generally speaking the widespread conversion of personal electronic appliances from vacuum tube to transistor The personal appliance transition from barrier-strip and point-to-point wiring technologies to PCB The two marketplace transitions from memory limited sprite based video displays in the 6502 era to early VGA era simple large memory backed bitmaps back to very complicated parallelized 3d accelerated video cards. The gradual marketplace conversion from simple voice phone in-band signaling to computerized out of band signaling from the 70s thru 90s. And I suppose the later marketplace conversion to voip. The marketplace conversion from computer full control front panels pre 1980 to various post 1980 mass storage bootstrap systems still used today. The marketplace era of closed source compilers, IDEs, languages, etc. There was a day back when you'd have to pay $5000 to compile Fortran and you liked it. Now the idea of paying anything for a compiler looks weird to most devs. The marketplace conversion from 4:3 squarish video to widescreen and the GUI designs that still haven't caught on to wide-screen-ness in the 2020s...
