What else was wildly cool about Flash was that the player itself was a shockingly tiny download -- even on 56K it was an incredibly fast download, and because we were all using MSIE then, the installation of this ActiveX thing that was the Flash Player required like one quick click and it was installed, and in 5 seconds you were seeing the Flash content.

Obviously the fact that it was that low-friction to install any non-sandboxed application code was a very naïve thing to allow, but I still have to hand it to the Macromedia developers for packing the whole player into such a tiny download and making it so frictionless. I'm pretty sure that had a HUGE impact on its adoption over say, Java applets. Java took a lot more time and effort to install, and while it had decent penetration (many "chat room" services and in-browser games like Yahoo Games used Java) it was never taken for granted that 'everyone has it' the way Flash was (until Steve Jobs singlehandedly burned that assumption to the ground with fire).
