Question: When did the venue of the The 29th Annual Kids' Choice Awards first open?

<P0-S0> Nickelodeon's 23rd Annual Kids' Choice Awards (Nickelodeon Kids' Choice Awards 2010) were held on March 27, 2010 (aired live from 8-9:30 p.m. ET) on the Nell and John Wooden Court of Pauley Pavilion, on the campus of UCLA in Los Angeles, California. <P0-S1>  With the launch of Nickelodeon Canada in late 2009, Canada broadcast the awards live as it aired in the Eastern, Central, and Mountain time zones of the United States (it was tape-delayed for the Pacific Time Zone) and the awards will be rebroadcast on YTV on April 2, 2010 at 7 p.m. ET. <P0-S2>  As a result, Canadian kids were able to vote on candidates for the first time. <P0-S3>  Nickelodeon's sister channels TeenNick and Nicktoons suspended regular programming during the 90-minute duration of the award show to allow viewers to see the awards. <P0-S4>  The 2010 awards were hosted by Kevin James, who is a first-time "Kids' Choice" host. <SEP> <P1-S0> Nickelodeon's 24th Annual Kids' Choice Awards were held on April 2, 2011, at 8 p.m. ET at the Galen Center at the University of Southern California in Los Angeles, California, US's University Park neighborhood due to renovations disallowing use of traditional venue Pauley Pavilion until at least 2013. <P1-S1>  Jack Black returned as host for the third time since 2006. <P1-S2>  The 2011 telecast was the first Kids' Choice Awards to take place in the month of April since 2006, as the previous four Kids' Choice telecasts from 2007 to 2010 were held on the last Saturday in March. <P1-S3>  Nominees were announced on February 10, 2011, for twenty categories. <P1-S4>  During the show, the Big Green Help Award was presented to Justin Timberlake, an honor given each year. <P1-S5>  More than 200 million record-breaking votes were cast for this year's 20-category awards. <SEP> <P2-S0>  Country singer Blake Shelton hosted the ceremony. <P2-S1> The 29th Annual Kids' Choice Awards was held live on March 12, 2016, at The Forum in Inglewood, California 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. <P2-S2>  A simulcast was also carried in the United States on sister channels Nicktoons, TeenNick, TV Land, and CMT, as well as on Nick Radio, to maximize ratings numbers, the show drew 3,321,000 on Nickelodeon and 4.426 million on all the channels put together. <SEP> <P3-S0>  Opening on December 30, 1967, the Forum was an unusual and groundbreaking structure. <P3-S1> The Forum is a multi-purpose indoor arena in Inglewood, California, adjacent to Los Angeles. <P3-S2>  Located between West Manchester Boulevard, across Pincay Drive and Kareem Court, it is north of the under-construction Los Angeles Stadium at Hollywood Park and the new Hollywood Park Casino. <P3-S3>  It is about three miles east of Los Angeles International Airport. <P3-S4>  Architect Charles Luckman's vision was brought to life by engineers Carl Johnson and Svend Nielsen, who were able to engineer the structure so that it had no major support pillars. <P3-S5>  This had previously been unheard of in an indoor arena the size of the Forum.
