What happened
Midway's 1992 arcade fighting game Mortal Kombat, created by programmer Ed Boon and artist John Tobias to compete with Capcom's Street Fighter II, featured graphic finishing moves that let winners execute defeated opponents on screen. Along with the full-motion-video horror game Night Trap, it drew the attention of the US Senate, and in December 1993 Senators Joe Lieberman and Herb Kohl held hearings scrutinizing video game violence, with Lieberman threatening to create a federal ratings commission if the industry did not regulate itself. In response, major publishers formed the Interactive Digital Software Association and launched the Entertainment Software Rating Board on 16 September 1994, with age-based categories such as 'Kids to Adults,' 'Teen,' and 'Mature.'
Why it matters
The ESRB headed off direct government regulation of game content and established the age-rating system still printed on every retail game box, signaling for the first time that games, like film, were treated as a medium serious enough to need content classification.
How we know
The ESRB's own official history page states its 1994 founding directly; The Strong National Museum of Play's entry on Mortal Kombat independently corroborates the congressional hearings and their direct link to the ratings board's creation.
