Thirteen years ago today, a name that would strike terror into the hearts of countless wannabe barbarians was first registered as a trademark in the United States. On May 31, 2005, World Wrestling Entertainment, Inc. was granted U.S. Registration No. 2957043 for the mark JOHN CENA for “Entertainment services, namely, wrestling exhibits and performances by a professional wrestler and entertainer; providing wrestling news and information via a global computer network.” Debuting in the ring in 2002, the name JOHN CENA has come to epitomize the “tough guy” image of professional wrestlers (and hulking brutes in general). While it is unclear whether John Cena could actually beat Chuck Norris in an Internet meme battle, both the 2957043 registration and John Cena himself are still in force.
