The 30th Annual Nickelodeon Kids' Choice Awards was held on March 11, 2017, at the Galen Center on the University of Southern California campus in Los Angeles live on Nickelodeon and either live or on tape delay across all of Nickelodeon's international networks and also served as a full-length TV movie. WWE superstar John Cena hosted the ceremony. This is the earliest Kids' Choice Awards ceremony date to take place, with the former latest being the 1989 ceremony on June 25, 1989.
A new episode of one of Nickelodeon's television series, Henry Danger, premiered right before the ceremony. Jace Norman subsequently led the transfer from the show to the ceremony. Afterwards, a sneak peak of a new series, Hunter Street, was shown.
Cena started his professional wrestling career in 1999 with Ultimate Pro Wrestling (UPW), and won the UPW Heavyweight Championship the following year. Cena signed a developmental contract with the World Wrestling Federation (WWF, later renamed to World Wrestling Entertainment, or simply WWE) in 2001, debuting on the WWE main roster in 2002.
From a generic character in 2002, Cena morphed into an arrogant and edgy rapper for the time period of 2002–2004, which earned him a huge stardom within the audience on SmackDown!. Cena later transitioned to his current character, which he describes as a "goody-two shoes Superman". However, Cena has been labeled as the "most polarizing professional wrestler ever" as his character has many supporters and many detractors. In 2012, IGN described Cena as WWE's franchise player since 2005 and in 2015, WWE credited Cena as being the "face of WWE". John Layfield and veteran industry personality and executive Paul Heyman referred to Cena as "the best wrestler ever". Heyman said about Cena that "no one has been able to keep that schedule, no one has matched his box-office appeal, no one has sold more merchandise, no one has had the longevity, the box-office attraction as the main, top level, box-office attraction than John Cena".
So far in his career, Cena has won 24 championships, with 15 reigns as a world champion (12 times as WWE Champion – with his last reign being as WWE World Heavyweight Champion – and three times as WWE's World Heavyweight Champion), five reigns as United States Champion, and four reigns as world tag team champion (two World Tag Team and two WWE Tag Team). Furthermore, he is a Money in the Bank ladder match winner (2012), a two-time Royal Rumble winner (2008, 2013), and a three-time Superstar of the Year Slammy Award winner (2009, 2010, 2012). Cena has the fourth-highest number of combined days as WWE Champion, behind Bruno Sammartino, Bob Backlund, and Hulk Hogan. He has also headlined WWE's flagship event, WrestleMania, on five different occasions (WrestleManias 22, 23, XXVII, XXVIII, and 29) over the course of his career. Along with The Undertaker and Triple H, Cena also has the most pay-per-view main event matches in WWE history at sixty-seven. As of 2016, John Cena is WWE's highest-paid wrestler.
Outside of wrestling, Cena has released the rap album You Can't See Me, which debuted at No. 15 on the US Billboard 200 chart, and starred in the feature films The Marine (2006), 12 Rounds (2009), Legendary (2010), The Reunion (2011), Trainwreck (2015), and Sisters (2015). Cena has also made appearances on television shows including Manhunt, Deal or No Deal, MADtv, Saturday Night Live, Punk'd, Psych, and Parks and Recreation. He was also a contestant on Fast Cars and Superstars: The Gillette Young Guns Celebrity Race, where he made it to the final round before being eliminated, placing third in the overall competition. Cena is also the host of American Grit on Fox. Cena is involved in numerous philanthropic causes; most notably with the Make-A-Wish Foundation. He has granted the most wishes in Make-A-Wish history.
