Back in the day I worked with a team that created training modules for products. We had a team of animators that was creating beautiful stuff. We had a cast of characters, voice talent, the whole shebang. It was very popular, especially in Asia where they loved the animated training.
Then the iPad came out. Our customers informed us that they were going to adopt the iPad for their on the floor training. Well, the iPad didn't support Flash so we had to rebuild everything to be HTML/CSS/JS only. It has been nearly 10 years and we are still using plain text, images, and the occasional video. We tried bringing back the interactive animations over the years, but nothing has come out that comes anywhere close to working as well as Flash did. It really sucks that despite nearly a decade no Flash replacement has emerged. I really feel like we lost something when Flash died. Interactive animations have been replaced with youtube videos and boring text and image web pages.
