Problem: Background: 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.
Context: The Joker debuted in Batman #1 (Spring 1940) as the eponymous character's first villain, shortly after Batman's debut in Detective Comics #27 (May 1939). The Joker initially appeared as a remorseless serial killer, modeled after a joker playing card with a mirthless grin, who killed his victims with "Joker venom": a toxin which left their faces smiling grotesquely. The character was intended to be killed in his second appearance in Batman #1, after being stabbed in the heart. Finger wanted the Joker to die because of his concern that recurring villains would make Batman appear inept, but was overruled by then-editor Whitney Ellsworth; a hastily drawn panel, indicating that the Joker was still alive, was added to the comic. The Joker went on to appear in nine of Batman's first twelve issues. The character's regular appearances quickly defined him as the archenemy of the dynamic duo, Batman and Robin; he killed dozens of people, and even derailed a train. By issue #13, Kane's work on the syndicated Batman newspaper strip left him little time for the comic book; artist Dick Sprang assumed his duties, and editor Jack Schiff collaborated with Finger on stories. Around the same time, DC Comics found it easier to market its stories to children without the more mature pulp elements that had originated many superhero comics. During this period, the first changes in the Joker began to appear, portraying him more as a prankster than threat; when he kidnaps Robin, Batman pays the ransom by check, meaning that the Joker cannot cash it without being arrested. Comic book writer Mark Waid suggests that the 1942 story "The Joker Walks the Last Mile" was the beginning point for the character's transformation into a more goofy incarnation, a period that Grant Morrison considered lasted the following thirty years. The 1942 cover of Detective Comics #69, known as "Double Guns" (with the Joker emerging from a genie lamp, aiming two guns at Batman and Robin), is considered one of the greatest superhero comic covers of the Golden Age and is the only image of the character using traditional guns. Robinson said that other contemporary villains used guns, and the creative team wanted the Joker--as Batman's adversary--to be more resourceful.
Question: What comic company released comics with the joker ?
Answer:

Background: Born in Drouin to Alfred and Colleen Ablett, Gary Ablett grew up in the Latrobe Valley in Victoria's Gippsland region alongside his four elder brothers and three sisters. Ablett displayed a love for sport at an early age, winning the state school high jump at 10 years of age. He was also awarded both club and competition best and fairest awards for Drouin at the under-11s, under-12s and under-14s levels. After citing waning interest in school, Ablett dropped out of high school at the age of 15 years to become a bricklayer's labourer.
Context: Ablett signed a one-year contract for the 1984 season with Geelong, and he began his first season under the guidance of Tom Hafey. He debuted for the Cats in Round 7 and after just nine games on the wing, Ablett was selected to his first State of Origin game for Victoria. Ablett earned best-on-ground honours after kicking 8 goals from the half-forward flank. He played 15 games and kicked 33 goals in the 1984 season, and was awarded the Carji Greeves Medal as the Geelong Football Club's "best and fairest" player of the year. Following his first season with Geelong, Ablett signed a new three-year contract with the club. Playing mostly on the half forward flank, Ablett won the club's goalkicking award for the following two seasons with 82 and 65 goals respectively. Although Ablett had developed a reputation for his laconic, lazy attitude to training under coach John Devine, this did not prevent him from earning top three placings in the best and fairest awards from 1985-87. With his contract expiring at the conclusion of the 1987 season, Ablett shocked the VFL by signing a new five-year contract with his former club, Hawthorn. After a "cooling-off" period, however, Ablett opted to remain with Geelong by agreeing to a lucrative five-year contract that tied him to the club for the long-term. Ablett began the 1988 season with 59 goals after just 11 games, placing him second on the goalkicking list behind Hawthorn's Jason Dunstall. In these games, he kicked 10 goals against Richmond in the Anzac Day game, and 11 against Brisbane--one shy of breaking the ground record of 12 goals at Carrara. Although he missed out on State honours and failed to place within the top three in the club best and fairest award, Ablett finished with 82 goals during the season for the second time in his career.
Question: How long did he play with the Cats?
Answer:
With his contract expiring at the conclusion of the 1987 season, Ablett shocked the VFL by signing a new five-year contract with his former club, Hawthorn.
