From the Super Mario Wiki
Reginald "Reggie" Fils-Aimé is the former president and Chief Operating Officer of Nintendo's North American branch. He is therefore responsible for all Nintendo-related activities in the United States, Canada, and Latin America, though he is widely known in other branches as well for his E3 performances. His career at Nintendo began in 2003 as Executive Vice President of Sales and Marketing, a position he held until 2006, when he was promoted to as president, replacing Tatsumi Kimishima, who had held the position since 2002.
Graduating Cornell University with a degree in Applied Economics in 1983, Reggie's management experience is not limited to his time at Nintendo. Since his graduation from Cornell, he has worked for Proctor & Gamble, Guinness, Panda Management Company, Derby Cycle Corporation, Pizza Hut, and most recently, VH1. Notable accomplishments of his at these establishments include the launching of the Bigfoot Pizza (Pizza Hut) and raising over thirty-five million dollars in disaster relief following the 2001 World Trade Center attacks (VH1).
Reggie gained notoriety among the gaming community at the 2004 Electronic Entertainment Expo (E3), where he introduced himself with the above quote. Many fans now know him as the "Regginator" (which eventually became his Mii's nickname), and he is attributed with sparking a new era for Nintendo, one of improved public relations, which fans and the press dubbed the "Reggielution". He has made regular appearances at subsequent E3s, being one of the three main sources of information for upcoming hardware and software (occasionally providing information on Nintendo's sales accomplishments and goals), the other two sources being Shigeru Miyamoto and Satoru Iwata. His most notable presentations introduced gamers to the Nintendo DS (E3 2004), the Game Boy Micro (E3 2005), specifications of the Nintendo 3DS (E3 2010), and the Wii U GamePad (E3 2011). He has also discussed and displayed trailers for a variety of games, including Super Mario Galaxy, Super Smash Bros. Brawl, and Luigi's Mansion: Dark Moon, and he has even personally demonstrated games, most notably Wii Fit and Wii Sports Resort (E3 2007 and E3 2008, respectively).
