Tom Fulp Built Newgrounds in 1995 and It Outlasted the Plug-In

From a Teenage Hobby Page to the Flash Internet's Central Address

Tom Fulp registered Newgrounds in 1995 as a personal site hosting his own crude browser games and animations, before Macromedia had acquired FutureSplash Animator and rebranded it as Flash. The earliest Newgrounds content was built in DHTML and Java applets; Flash arrived on the site gradually in the late 1990s, but by 2000 it had become the platform's exclusive creative medium and its primary reason for existing. That alignment — one site, one plug-in, one rapidly expanding community of teenage animators — is the structural fact that explains Newgrounds' influence on everything that followed.

What Fulp built was not, in the first instance, a portal in the sense that Miniclip or Armor Games were portals. Those operations acquired or licensed content from external developers and curated it for a general audience. Newgrounds was a submission platform: anyone could upload a SWF file and it would appear on the site, rated by viewers and sorted into a running front page by score. The voting system was called the Portal, and the Portal was genuinely open — which meant Newgrounds accumulated content ranging from polished animation to deliberately offensive shock pieces, often within the same week. Fulp moderated with a comparatively light hand through the early 2000s, a decision that drew criticism and simultaneously attracted creators who had nowhere else to go.

The content policy, such as it was, drew a line at illegal material and at anything involving minors, but left violence, adult themes, and experimental or disturbing work largely untouched. This is why David Firth's Salad Fingers found its audience on Newgrounds in 2004 rather than anywhere else: the site's tolerance for unsettling work without obvious commercial application was structural, not accidental. The same logic explains why Fulp's own game Pico's School — a darkly comedic school-shooting parody released in 1999 — remained on the site through multiple platform controversies. Newgrounds hosted things that other portals would not, and it did so consistently enough that creators learned to rely on it.

The Economics of Not Having a Sponsorship Requirement

The portal sponsorship economy that developed through the mid-2000s largely ran alongside Newgrounds rather than through it. Developers sold branding rights to portals whose logos then appeared in a game's preloader; Newgrounds had its own sponsorship arrangements and advertising revenue, but it never required uploaded work to carry external branding, and it never positioned itself purely as a distribution vehicle for commercially sponsored content. Mochi Media's ad network, which embedded advertising inside SWF files and paid developers per impression, integrated with Newgrounds but was not exclusive to it, and Newgrounds operated its own supporter subscription model that predated most other portals' monetisation experiments.

The site never adopted a strategy of converting its archive to video or accepting that the interactive work was simply gone.

This independence gave Newgrounds a different creative texture. Edmund McMillen built the Meat Boy prototype in Flash and posted it to Newgrounds in 2008; the site's community response was part of what demonstrated that a harder, more demanding game could find an enthusiastic audience. Canabalt, Adam Saltsman's one-button runner built in five days in 2009, circulated widely on Newgrounds before it reached other portals. The Behemoth's Alien Hominid began as a Newgrounds submission in 2002 and ended up on three home consoles — a trajectory that was legible to Fulp's community in a way it would not have been on a pure casual-game portal, because Newgrounds readers understood the creator's name as well as the title.

Fulp formalised this creator-forward identity through the Newgrounds Audio Portal, launched in 2003, and later through the Art Portal. Both allowed creators to build verifiable track records under consistent identities — a function that mattered practically when developers moved into commercial work and needed to demonstrate an audience and a body of prior work. FlashGameLicense later codified the brokerage side of that relationship, but Newgrounds had already established that a Flash creator's profile page was a professional document.

After the Plug-In Died

Adobe's end-of-life announcement in July 2017 and the kill-switch activation on 12 January 2021 presented Newgrounds with a problem no other portal faced in the same form: its entire archive of more than a decade's creative output was in a format that would no longer execute in any standard browser. Fulp's response was to become one of the earliest and most committed institutional partners of the Ruffle project — the open-source Flash Player re-implementation written in Rust and compiled to WebAssembly. Newgrounds integrated Ruffle into its playback infrastructure and made it the site's default player for SWF content, meaning that a substantial portion of the archive became accessible again without requiring users to maintain a legacy Flash installation. The integration was not seamless — ActionScript 3 support in Ruffle lagged behind AS1 and AS2 compatibility, and complex games dependent on AVM2 features remained broken for longer — but Newgrounds committed engineering effort to the project rather than simply waiting for upstream progress.

The Flashpoint project, BlueMaxima's offline archival initiative, had by early 2025 catalogued over 100,000 entries, and a significant fraction of that collection originated as Newgrounds submissions. The two projects are complementary rather than redundant: Flashpoint provides guaranteed offline playback independent of any live site, while Newgrounds continues to publish new work. Creators still submit SWF files, but they also submit content built in HTML5 and other formats, and the community infrastructure — the review system, the author profiles, the audio and art portals — remained operational. The site never adopted a strategy of converting its archive to video or accepting that the interactive work was simply gone.

Newgrounds was not the only Flash portal, and in raw traffic it was probably not the largest at the peak of the format's dominance. But it is the portal that maintained a continuous institutional identity, kept its founder in active editorial involvement, bet on open-source emulation rather than abandonment, and survived into the post-Flash era as a functioning creative community rather than a legacy brand licensing a catalogue. That is a specific set of choices, made across three decades, by a person who still moderates the front page.
