From Homestar Runner to Salad fingers to badgers, stick figure battles, and the End of Ze World, this — dare I call it an artform? — was a cultural touchstone for a generation.
Flash made vector animation available to the masses, and internet distribution of the relatively small video files was a piece of cake. With the filetype now essentially deprecated, the creators gone on to bigger and better things, the distribution sites shut down, it is a dead form. Most of it will be lost forever, although there may be someone archiving some of it for posterity.
They’re not lost, most of them are archived via Flashpoint. The most notable ones have also been exported as regular videos on sites like Newgrounds. But yeah, I miss that Flash era where people made fun animations and games for whatever was on their mind.
