Underground fighting has been banned or restricted at least a dozen times since 1700. Each time, it resurfaces in a different form. The pattern is consistent: regulation pushes fighting underground, technology or cultural shifts bring it back to visibility.
Three technologies transformed underground fighting:
- DVD/VHS (1990s-2000s) - Enabled distribution of Felony Fights and early recordings
- YouTube (2005-present) - Democratized distribution and created sustainable revenue models
- Social media (2015-present) - Instagram, TikTok, and Telegram expanded audience reach exponentially
- 1700s-1900s: England and Ireland dominant
- 1900s-1960s: United States becomes the center
- 1960s-1990s: Brazil (Vale Tudo) and Southeast Asia (Lethwei) emerge
- 2000s-2010s: Russia and Eastern Europe produce major promotions
- 2020s: Global distribution with active scenes on every inhabited continent
