it weren't for you meddling kids." As such, it returns to the formulaic version of humans in monster disguises, rather than the real monsters and ghosts of the prior four direct-to-video films (or the 1980s versions that preceded them). The show was produced by Warner Bros. Animation, the successor to Warner Bros. Cartoons which was the studio famous for bringing the Looney Tunes/Merrie Melodies to life, which had by this time absorbed Hanna-Barbera Productions in 2001, after being bought by Time Warner from Turner Broadcasting System since their merger on October 10, 1996. As is the standard for other classic Hanna-Barbera properties (Yogi Bear, The Flintstones, Wacky Races, etc.), the studio is still credited as the copyright owner, and Joseph Barbera, co-founder and co-chairman of the Hanna-Barbera studios, served as an executive producer alongside Sander Schwartz. William Hanna, longtime partner of Barbera, had died the year before. Wang Film Productions, DongWoo Animation Co. Ltd, and Lotto Animation contributed some of the animation for this series. It is the first Scooby-Doo series to be produced in 16:9 widescreen, although it was cropped in 4:3 when broadcast. The band Simple Plan is strongly connected to What's New, Scooby-Doo?. They perform the theme song (written by Rich Dickerson), and appeared as themselves in the episode "Simple Plan and the Invisible Madman". Two of their songs appeared in chase scenes: "I'd Do Anything" in the episode "It's Mean, It's Green, It's the Mystery Machine" and "You Don't Mean Anything" in "Simple Plan and the Invisible Madman", which also had the song "The Worst Day Ever" serve as the song the band plays during a scene where they practice, and a scene where they are in concert. Also, they contributed to the theatrical movie Scooby-Doo 2: Monsters Unleashed. Each season included one holiday-themed special along with the other 13 regular episodes. The first season's special was A Scooby-Doo Christmas (2002), followed by A Scooby-Doo Halloween (2003) and A Scooby-Doo Valentine (2005). What's New aired for three seasons on The WB Television Network's "Kids' WB" programming block as a half-hour program, before being put on an indefinite hiatus in 2005, although the last episode, "E-Scream", was aired on Cartoon Network. Reruns have been shown on both Cartoon Network and its sister channel Boomerang. It also debuted on Boomerang and Cartoon Network in the United Kingdom and Ireland. In the United Kingdom, it aired on CBBC from
