Tour de France Soundtracks: Tour de France Soundtracks is the tenth studio album by the German electronic group Kraftwerk, released in August 2003.  It was re-released in October 2009 under the title Tour de France.  The album was recorded for the 100th anniversary of the first "Tour de France" bicycle race, although it missed its intended release date for the actual tour.  It includes a new recording of their 1983 single of the same name, the cover artwork of both releases being nearly identical.  The announcement of the release caused much anticipation, as it had been 17 years since the group had put out a full album of new studio material (1986's "Electric Café", also known as "Techno Pop").

Jean Kerléo: Jean Kerléo (born 24 February 1932) is a French perfumer who worked in-house of Jean Patou and is also the founder of the Osmothèque, a scent archive in Versailles.  Kerleo was born on 24 February 1932 in Brittany, France.  At age 22, he began making perfumes for a New York City company, Helena Rubenstein.  He received the Prix des Parfumeurs de France in 1965, served as the president for the Society of French Perfumers from 1976 to 1979, and was awarded the Prix François COTY in 2001

Two Worldwide Plaza is a residential condominium tower west of the center of the block, and Three Worldwide Plaza is a low-rise condominium residential building with street level stores on Ninth Avenue, to the west of the towers.

LGBT culture in New York City: New York City has one of the largest and most prominent LGBT populations in the world.  Brian Silverman, the author of "Frommer's New York City from $90 a Day", wrote the city has "one of the world's largest, loudest, and most powerful" LGBT communities" and "Gay and lesbian culture is as much a part of New York's basic identity as yellow cabs, high-rises, and Broadway theater."  LGBT Americans in New York City constitute by significant margins the largest self-identifying lesbian, gay, bisexual and transgender communities in the United States, and the 1969 Stonewall Riots in Greenwich Village are widely considered to be the genesis of the modern gay rights movement.  As of 2005, New York City was home to an estimated 272,493 self-identifying gay and bisexual individuals.  The New York City metropolitan area had an estimated 568,903 self-identifying GLB residents.  Meanwhile, New York City is also home to the largest transgender population in the United States, estimated at 25,000 in 2016.

New York City English: New York City English, or Metropolitan New York English, is a regional dialect of American English spoken by many people in New York City and much of its surrounding metropolitan area.  Described by sociolinguist William Labov as the most recognizable dialect in North America, the dialect is known through its association in the media with many public figures and fictional characters.  Its features are most densely concentrated in New York City proper and its immediate suburbs (whose residents often commute to New York City), but they also extend somewhat to the wider metropolitan area and the New York City diaspora in other regions.

National Actors Theatre: The National Actors Theatre (NAT) was a theatre company founded in 1991 by Tony Randall, whose dream it was to create such an organization.  He was chairman until his death in 2004, when the theatre also subsequently closed down.  At first the company was housed at the Belasco Theatre, New York, then at the nearby Lyceum Theatre, and in 2002 was based in the Michael Schimmel Center for the Arts at Pace University in New York City.  It was the only professional theatre company housed in a university in New York City.

Katherine Oliver: Katherine Oliver is an American media and entertainment executive based in New York City.  Oliver is currently a Principal at Bloomberg Associates, a philanthropic consultancy firm founded by Michael Bloomberg to provide advice and long-term solutions to cities worldwide.  On August 1, 2002, she was appointed by New York City Mayor Michael Bloomberg as the Commissioner of The New York City Mayor's Office of Film, Theatre and Broadcasting, which facilitates all aspects of film, television and commercial production in New York City, coordinating on-location filming, liaising with the community and promoting the City as an entertainment capital.  Oliver was the main liaison between the Mayor's Office and Hollywood and aimed "to make filmmakers and production companies happy to return to New York."  In 2013, Oliver and Mayor Bloomberg were featured on the cover of Variety and were credited for their role in "revitalizing the city's entertainment sector."  An economic impact study released by the Boston Consulting Group in 2012 found that New York City's entertainment industry during Oliver's tenure as film commissioner had grown to account for a $7.1 billion annual direct spend in New York City, an increase of $2 billion since 2002, and that the local industry created 30,000 jobs in New York City since 2004, growing to employ 130,000 people.  AM New York noted that: "New York's film and TV industry is stronger than it has ever been, pumping $7.1 billion into the local economy in 2011 and bringing in some $60 billion over the last decade."  After Bloomberg announced that former president and co-founder of NYC Media Group Arick Wierson was returning to the private sector, Bloomberg named Oliver as the incoming president of NYC Media and general manager of NYCTV.  In July 2010, Oliver became the commissioner of the Mayor's Office of Media and Entertainment, the city agency that includes the Mayor's Office of Film, Theatre and Broadcasting, NYC Media, and NYC Digital.

New York City Police Museum: The New York City Police Museum (NYCPM) celebrates the history and contributions of the New York City Police Department, established in 1845.  The museum is located in Lower Manhattan in New York City, near Wall Street and the South Street Seaport.  While one of the museum's primary focuses is a memorial to September 11th, the museum contains a wide range of information on the history of the NYPD.  The museum, which grew from a gallery housed at the New York City Police Academy, opened at 26 Broadway at Bowling Green in January 2000 and re-opened in a new location at 100 Old Slip, former home of the First Precinct, in January 2002.  In October 2012, Hurricane Sandy caused substantial damage at 100 Old Slip, and the museum reopened on October 24, 2013 at 45 Wall Street.  That location closed in 2014 and the museum's future plans are unclear.
