Browser gaming began as a side channel rather than a primary industry. Early websites hosted lightweight puzzles, arcade recreations, and racing titles that required nothing beyond a Flash plugin and a slow dial-up connection. These games proved that entertainment did not need a disc, a console, or a purchase — only a URL and a few minutes of spare time.
Over two decades, that amateur foothold matured into professional distribution networks. Platforms emerged that indexed thousands of titles, standardized genre categories, and updated catalogs daily. The medium expanded from novelty demos to competitive IO games, streaming ports of classic franchises, and fully realized indie experiments hosted on marketplaces like itch.io.
