In what year did Grey's Anatomy premiere?

Grey's Anatomy premiered in 2005. The medical drama debuted on ABC on March 27, 2005, introducing Meredith Grey and her fellow surgical interns at Seattle Grace Hospital.

Created by Shonda Rhimes, the series began as a midseason replacement rather than as part of ABC's autumn schedule. Its first season followed Meredith, Cristina Yang, Izzie Stevens, George O'Malley, and Alex Karev as they started demanding surgical internships under Miranda Bailey and Chief of Surgery Richard Webber.

A common mix-up is confusing the show's premiere year with the year of its pilot's production or with later landmark seasons. The first episode, "A Hard Day's Night," aired in March 2005. The series was initially planned around a relatively small first season, but strong ratings and audience interest helped it become one of television's longest-running scripted dramas.
