Question: When was the interior of the location of the 1997 MTV Video Music Awards declared a city landmark?
Context: Radio City Music Hall is an entertainment venue located in Rockefeller Center in New York City.  Nicknamed the "Showplace of the Nation", it was for a time the leading tourist destination in the city.  Its interior was declared a city landmark in 1978, and the venue is notable as the headquarters for the precision dance company, the Rockettes.

Jost's work with Tokio Hotel lead to 87 media-awards, including 4 MTV European Music Awards, the MTV Video Music award Japan, 4 MTV Latin Music Awards including song of the year for "Monsoon" and also the US MTV Video Music Award (Moonman).  Even though Jost managed several careers of big media artists, he only rarely answers interviews for the press and is known for principally never giving TV interviews.  For his work as a songwriter, Jost was named Germany's best songwriter (Rock & Pop) by the GEMA (the German equivalent to the ASCAP/BMI).  Jost is currently working in his Los Angeles studios. The 1997 MTV Video Music Awards aired live on September 4, 1997, honoring the best music videos from June 17, 1996, to June 16, 1997.  The show was hosted by Chris Rock at Radio City Music Hall in New York City. An MTV Video Music Award (commonly abbreviated as a VMAs) is an award presented by the cable channel MTV to honor the best in the music video medium.  Originally conceived as an alternative to the Grammy Awards (in the video category), the annual MTV Video Music Awards ceremony has often been called the "Super Bowl for youth", an acknowledgment of the VMA ceremony's ability to draw millions of youth from teens to 20-somethings each year.  By 2001, the VMA had become a coveted award.  The statue given to winners is an astronaut on the moon, one of the earliest representations of MTV, and was colloquially called a "moonman".  However, in 2017 Chris McCarthy, the President of MTV, stated that the statue would be called a "Moon Good Charlotte's songs and albums have received recognition at the MTV Australia Awards, the MTV Europe Music Awards, and the MTV Video Music Awards. " The Anthem" is the second single from the band's second album "The Young and the Hopeless".  The song was awarded the "Best Rock Video" award from the MTV Video Music Awards Japan and the "Peoples Choice: Favorite International Group" award from the MuchMusic Video Awards.  The band itself has received awards including "Fave International Band" at the Nickelodeon Australian Kids' Choice Awards, "Best International Group" at the NRJ Music Awards, and "Best International Rock Act" at the TMF Awards.  As of July 2008, Good Charlotte has received eight awards from twenty nominations. The MTV Video Music Award for Best Dance Video was first awarded in 1989, and it was one of the original four genre categories that were added to the MTV Video Music Awards that year.  With a revamp of the awards in 2007, the category was cut out along with several others, yet it returned for the 2008 awards, where it was given a new name: Best Dancing in a Video.  In 2009 the award for Best Dancing was again eliminated from the VMAs, but it was revived again in 2010 as Best Dance Music Video.  The following year, though, the award was once again absent from the category list.  Once again, the award was revived in 2012, this time under the name of Best Electronic Dance Music Video, celebrating the rise in popularity of EDM throughout the year.  It was again eliminated for the 2013 awards.  On July 17, 2014, MTV brought the category back, this time renaming it the MTV Clubland Award for the 2014 Awards.  The pattern of awarding the moonman every other year continued in 2016 where the award was renamed Best Electronic Video. The 2006 MTV Video Music Brazil was hosted by Cazé Peçanha, Marcos Mion and Daniela Cicarelli and took place at the Credicard Hall.  It was the last year where VMB focused on awarding music videos (like the MTV Video Music Awards); from 2007 on, VMB's categories were redefined to focus on the artists (like the MTV Europe Music Awards). American singer-songwriter Taylor Swift has released four video albums and has appeared in thirty-eight music videos, five films and three television shows.  From her eponymous debut album (2006), she released music videos for the singles "Tim McGraw", "Teardrops on My Guitar", "Our Song", and "Picture to Burn", all directed by Trey Fanjoy and released from 2006–08.  For the second of these, she earned an MTV Video Music Award for Best New Artist nomination.  She followed with three other music videos in 2008—"Beautiful Eyes" from her extended play of the same name, "Change" from the "AT&T Team USA Soundtrack" and "Love Story" from her second album "Fearless" (2008).  The latter was nominated for two awards at the 2009 CMT Music Awards—Video of the Year and Female Video of the Year.  For the video of "You Belong with Me" she won Best Female Video at the 2009 MTV Video Music Awards.  During her acceptance speech, she was interrupted by rapper Kanye West, which sparked controversy and received much media attention. The MTV Video Music Brazil awards (originally Video Music Awards Brazil), more commonly known as VMB, were MTV Brasil's annual award ceremony, established in 1995.  MTV viewers picked the winners for most categories since 2001.  Unlike in the MTV Video Music Awards, the most important category at the MTV Video Music Brazil was the Viewer's Choice, not the Video of the Year; both of these categories merged in 2005.  In 2007, the awards have faced a major rebranding, with several categories extinguished (most notably the specific genre divisions) and even the trophies' design changed; from this year on, the awards were no longer focused on music videos, but on the artists, and the most important category became the Artist of the Year.  However, the Video of the Year category existed to award the best music video. The MTV Video Music Award for Best Alternative Video (also known as Best Alternative Music Video) was first given out at the 1991 MTV Video Music Awards.  Prior to the award being called Best Alternative Video, this award was known as MTV Video Music Award for Best Post-Modern Video in 1989 and 1990.  The last of this award was given out in 1998 to Green Day for their song "Good Riddance (Time of Your Life)".  After the award's discontinuation, artists and videos who would have normally been eligible for this award became eligible for other genre categories, including Best Rock Video.
