La storia

COME SWF

SWF — originally "ShockWave Flash", later backronymed to "Small Web Format" — was created by FutureWave Software in 1996 as the playback format for their FutureSplash Animator. Macromedia acquired FutureWave in December 1996 and renamed the product Flash. Adobe then acquired Macromedia in 2005, inheriting Flash and SWF.

For 15 years SWF files powered a huge chunk of the interactive web: Newgrounds animations, restaurant websites with music, Farmville and millions of casual games, interactive infographics, YouTube’s video player until 2010. At its peak, over 99% of desktop computers could play SWFs. Then Apple’s 2010 iPhone-no-Flash stance, mobile’s rise, and HTML5 slowly strangled the platform. Adobe officially killed Flash Player on December 31, 2020. SWF files still exist in vast archives (the Internet Archive’s Flash Emulator preserves tens of thousands) but are culturally and commercially extinct.

CURIOSITÀ E
ANEDDOTI.

The Internet Archive runs Ruffle, an open-source Flash emulator in WebAssembly, so tens of thousands of archived SWF animations still play in modern browsers.

Newgrounds, the 2000s animation portal, hosted hundreds of thousands of SWF animations — the cultural birthplace of many animators still working today.

Steve Jobs' 2010 "Thoughts on Flash" essay — refusing Flash on iPhone — is widely credited with starting the platform's decline.

YouTube's original video player (2005-2010) was a SWF file — every early YouTube video played through Flash.

Adobe officially killed Flash Player on December 31, 2020, and actively disabled it in browsers via Windows updates.

Limitazioni
