Heh! Yes, it's gotten so that Mountain Lion won't even let you install a Flash update unless it's signed from Adobe and the latest version. A sad necessity though when there are tons of web sites that will pop up a message that you need the latest version of Flash to view their site, when what you really end up downloading and installing is a Trojan of some sort.
Shockwave is actually a bit older than Flash. It was first released in 1995, Flash in 1996. Not sure what the difference between them is since they both seem to be for animated web content.
