Today marks the twentieth anniversary of the premiere of Batman Beyond. The series debuted on January 10th, 1999 and lasted until December 18th, 2001 on, running for fifty-two episodes across three seasons as well as featuring a direct-to-video feature. Partially inspired by Marvel's 2099 line, the series served as an epilogue to the wildly popular Batman: The Animated Series and is set in DC's Animated Universe. The series followed young teenager Terry McGinnis, who stumbles across the elderly Bruce Wayne's secret as the retired Batman. He takes up the mantle to continue protecting the city while uncovering the secret of his father's murder.
The announcement of the series was criticized but once it began airing it became extremely popular. It has become one of the most popular depictions of the Dark Knight, with fans praising the darker and more emotional story moments. It was nominated for numerous Emmys and Annie Awards, winning several. The series did spawn its own spin-off in The Zeta Project. Unfortunately, when Justice League was announced, the proposed fourth season was shelved. It did not get a proper series finale until the "Epilogue" episode of Justice League Unlimited. The characters have continued on in comic book form.
