It was 15 years ago today that the video game industry introduced the ESRB rating system to Congress, reports Wired's This Day in Tech blog.

The move came in the wake of Congressional criticism of game violence, particularly the original Mortal Kombat, which seems laughably tame by today's standards. Wired's Chris Kohler writes:

The [Congressional] hearings were largely a response to the popularity of... Mortal Kombat...

Nintendo chairman Howard Lincoln and Sega vice president Bill White took potshots at each other during the hearing. Lincoln said that the Sega CD game Night Trap, another photorealistic, occasionally violent game that the company had rated MA-17, “simply has no place in our society” and testified that “small children” had bought it.

Meanwhile, White’s position was that Sega was more responsible than Nintendo, because his company had [its own] rating system in place...  [Connecticut Sen. Joe] Lieberman would later express his shock that the two executives went after each other with such ferocity.

Lieberman's threat to regulate game content via legislation persuaded the game biz to get its act together. The IDSA (now known as the ESA) was formed and quickly set up the ESRB, which went into operation on September 1st, 1994.
