Worldwide Day of Play is an annual event designed to encourage children and parents to turn off the television and play, especially outdoors. The yearly event officially began on all US Nickelodeon channels, including Nickelodeon, Nick GAS (until 2007), Nick Jr. (formerly called Noggin), TeenNick (formerly called The N), and NickToons, on October 1, 2005. The event was first shown on October 2, 2004 on Nickelodeon. Some foreign versions of Nick also participated. The event is designed as a finale for Nick's six-month long Let's Just Play campaign. In addition, Nick.com would also have special features for children to learn how to stay active and healthy.
