... and the fact that even with a browser, content gated behind Macromedia Flash or ActiveX applets was / is not indexable is why Google pushed so hard to expand HTML5 capabilities.
Was it really a success though in that regard? HTML5 was great and all, but it never did replace Flash. Websites mainly just became more static. I suspect the lack of mobile integration had more to do with Flash dying than HTML5 getting better. It's a shame in some sense, because Flash was a lot of fun.
