Actually Macromedia didnt invent it either. A small company called "FutureSplash" had a software called FutureSplash Animator. Macromedia bought it in the late 90s
That's disingenuous. Adobe didn't invent Flash, they bought the company that did. Adobe's strategy is based on them having resources to acquire, not create.
Cringe!
Adobe bought Flash and Shockwave along with Macromedia that invented them 10 year earlier.
