March 25 (UPI) -- ABC has renewed Grey's Anatomy for a 20th season.
The show will now be the television's longest running medical drama.
Meg Marinis will serve as showrunner, replacing outgoing writer-producer Krista Vernoff.
It is unclear who from the current cast will return for the next run of the series, which was created by Emmy-winner Shonda Rhimes.
Mainstay Ellen Pompeo, who reduced her appearances this season to work on other projects, is expected to continue as a producer on the show and at least guest star.
