I remember images loading one line at a time. Now I can stream 4k video. Not sure what OP is on about. There is lots of bloat but we are now on a jumbo jet and we used to be on a hot-air balloon
Somewhere around 1998 or 1999 I was working as a web developer and I listened to a pitch from a guy who wanted to build a video streaming site. For the life of me, I couldn't figure out who was going to pay a subscription to watch grainy, postage-stamp sized videos in a web browser, but apparently that sort of thing took off.
