Green Lantern is an ongoing American comic-book series featuring the DC Comics heroes of the same name. The character's first incarnation, Alan Scott, appeared in All-American Comics #16 (July 1940), and was later spun off into the first volume of Green Lantern in 1941. After 38 issues, that series was cancelled in 1949. When the Silver Age Green Lantern, Hal Jordan, was introduced, the character starred in a new volume of Green Lantern starting in 1960.
Although Green Lantern is considered a mainstay in the DC Comics stable, the series has been cancelled and rebooted several times. The first series featuring Hal Jordan was cancelled at issue #224, but was restarted with a third volume and a new #1 issue in June 1990. When sales began slipping in the early 1990s, DC Comics instituted a controversial editorial mandate that turned Jordan into the supervillain Parallax and created a new protagonist named Kyle Rayner. This third volume ended publication in 2004, when the miniseries Green Lantern: Rebirth brought Hal Jordan back as a heroic character and made him the protagonist once again. After Rebirth's conclusion, writer Geoff Johns began a fourth volume of Green Lantern from 2005 to 2011, and a fifth volume which started immediately after, this time initially showcasing both Hal Jordan and Sinestro as Green Lanterns.
