Sega Scream
From Sega Retro
The Sega Scream was an advertising campaign done by SEGA up until 1996. It discovered its loud brand weapon while shooting a TV commercial in the early '90s. A worker on the set suggested, "Hey, why don't you guys have someone scream Sega at the end?" From there, Tom Kalinske approved its implimentation in ads and the rest is history.
In 2000, then-CEO Peter Moore decided to bring back the Sega scream and three different ads incorporating it were debuted during the MTV Music Video Awards. In one of the three, "Civil War", [[Seaman] delivered the scream at the end.
