Question:
The Joker is a fictional supervillain created by Bill Finger, Bob Kane, and Jerry Robinson who first appeared in the debut issue of the comic book Batman (April 25, 1940), published by DC Comics. Credit for the Joker's creation is disputed; Kane and Robinson claimed responsibility for the Joker's design, while acknowledging Finger's writing contribution. Although the Joker was planned to be killed off during his initial appearance, he was spared by editorial intervention, allowing the character to endure as the archenemy of the superhero Batman. In his comic book appearances, the Joker is portrayed as a criminal mastermind.
The Joker was one of the few popular villains continuing to appear regularly in Batman comics from the Golden Age into the Silver Age, as the series continued during the rise in popularity of mystery and romance comics. In 1951, Finger wrote an origin story for the Joker in Detective Comics #168, which introduced the characteristic of him formerly being the criminal Red Hood, and his disfigurement the result of a fall into a chemical vat.  By 1954, the Comics Code Authority had been established in response to increasing public disapproval of comic book content. The backlash was inspired by Frederic Wertham, who hypothesized that mass media (especially comic books) was responsible for the rise in juvenile delinquency, violence and homosexuality, particularly in young males. Parents forbade their children from reading comic books, and there were several mass burnings. The Comics Code banned gore, innuendo and excessive violence, stripping Batman of his menace and transforming the Joker into a goofy, thieving trickster without his original homicidal tendencies.  The character appeared less frequently after 1964, when Julius Schwartz (who disliked the Joker) became editor of the Batman comics. The character risked becoming an obscure figure of the preceding era until this goofy prankster version of the character was adapted into the 1966 television series Batman, in which he was played by Cesar Romero. The show's popularity compelled Schwartz to keep the comics in a similar vein. As the show's popularity waned, however, so did that of the Batman comics. After the TV series ended in 1968, the increase in public visibility had not stopped the comic's sales decline; editorial director Carmine Infantino resolved to turn things around, moving stories away from schoolboy-friendly adventures. The Silver Age introduced several of the Joker's defining character traits: lethal joy buzzers, acid-squirting flowers, trick guns, and goofy, elaborate crimes.

Question:
The Rock and Roll Hall of Fame, located on the shore of Lake Erie in downtown Cleveland, Ohio, recognizes and archives the history of the best-known and most influential artists, producers, engineers, and other notable figures who have had some major influence on the development of rock and roll. The Rock and Roll Hall of Fame Foundation was established on April 20, 1983, by Atlantic Records founder and chairman Ahmet Ertegun. In 1986, Cleveland was chosen as the Hall of Fame's permanent home. Since opening in September 1995, the "Rock Hall" - part of the city's redeveloped North Coast Harbor - has hosted more than 10 million visitors and had a cumulative economic impact estimated at more than $1.8 billion.
The Rock and Roll Hall of Fame and Museum produces numerous public programs, including concerts, interviews, lectures, film screenings, and other events that help tell the story of rock and roll. Every February, the museum celebrates Black History Month by hosting concerts, film screenings and lectures that illustrate the important role African-Americans have played in the history of rock and roll. Since the program began in 1996, such artists as Robert Lockwood, Jr., the Temptations, Charles Brown, Ruth Brown, the Ohio Players, Lloyd Price, Little Anthony and the Imperials, and Al Green have appeared at the museum during Black History Month.  Another program is the Hall of Fame Series. This series began in April 1996 and features interviews with Hall of Fame inductees in a rare and intimate settings, most often in the Museum's Foster Theater. The interviews are usually followed by a question-and-answer session with the audience and, often, a performance by the inductee. Among the inductees who have taken part in this series are Darryl "DMC" McDaniels of Run-D.M.C., Lloyd Price, Marky Ramone, Seymour Stein, Ray Manzarek of the Doors, Ronnie Spector, Bootsy Collins, Ann and Nancy Wilson of Heart, and Jorma Kaukonen of the Jefferson Airplane.  A similar program is the Legends Series. The only real difference between this program and the Hall of Fame Series is that it features artists who have not yet been inducted into the Hall of Fame. Peter Hook of Joy Division, Spinderella of Salt n Pepa, Tommy James, and the Chi-Lites are among the artists who have participated in the Legends Series.  The Rock and Roll Hall of Fame and Museum's most acclaimed program is the annual American Music Masters series. Each year the museum celebrates one of the Hall's inductees with a week-long series of programs that include interviews, film screenings, and, often, a special exhibit. The celebration ends with an all-star concert held at a Cleveland theater. The concerts include a diverse mix of artists, from Hall of Fame inductees to contemporary musicians.  The American Music Masters series began in 1996 with Hard Travelin': The Life and Legacy of Pete Seeger. Since then, the programs have honored the following inductees: Jimmie Rodgers (1997), Robert Johnson (1998), Louis Jordan (1999), Muddy Waters (2000), Bessie Smith (2001), Hank Williams (2002), Buddy Holly (2003), Lead Belly (2004), Sam Cooke (2005), Roy Orbison (2006), Jerry Lee Lewis (2007), Les Paul (2008), Janis Joplin (2009), Fats Domino and Dave Bartholomew (2010), Aretha Franklin (2011), and Chuck Berry (2012).
