ABC’s medical drama Grey’s Anatomy continues to secure its place in TV history with a two-year renewal for seasons 16 and 17. The series’ star, Ellen Pompeo, is set for both seasons, along with the other original cast members.

Additionally, ABC has renewed two other Shondaland series, Grey’s Anatomy spinoff Station 19 for a third season and How to Get Away with Murder for a sixth season (Legal drama For the People has been canceled). Grey’s Anatomy executive producer/showrunner Krista Vernoff will helm both the medical drama and Station 19, providing a seamless crossover narrative on both series. All series come from ABC Studios.

This season, Grey’s Anatomy, created by Shonda Rhimes, surpassed NBC’s ER as the longest-running primetime medical drama in TV history in number of episodes (341 to 331 for the NBC staple),

Now Grey’s Anatomy also will become the longest-running medical drama in a number of seasons, 17 vs. 15 for ER.

Grey’s Anatomy, which also cemented its place last season in ABC’s history books as the network’s longest-running primetime scripted series, has continued to be a powerful ratings performer for the network as its top scripted series.

Season-to-date, Grey’s has averaged a 2.8 rating and 3.6 million viewers in the key 18-49 demo and 10 million total viewers (Live+7). Its recent crossover episode with spinoff Station 19 was another boost for the series, which gave it its biggest audience in five weeks (700k viewers).

Created and executive produced by Rhimes, Grey’s Anatomy follows Meredith Grey (Ellen Pompeo) and the team of doctors at Grey Sloan Memorial, who are faced with life-or-death decisions on a daily basis. They seek comfort from one another, and, at times, more than just friendship. Together they discover that neither medicine nor relationships can be defined in black and white.

“Everyone at Shondaland is thrilled that our fans’ commitment to TGIT continues,” said Shonda Rhimes and producing partner Betsy Beers in a joint statement. “We are so proud of Krista and (HTGAWM’s) Pete (Nowalk) and the work they do. Making the choice to have Krista oversee Station 19 was easy — the creativity she brings to the Grey’s Anatomy universe continues a tradition of storytelling we hold dear.”

Grey’s Anatomy stars Pompeo as Meredith Grey, Justin Chambers as Alex Karev, Chandra Wilson as Miranda Bailey, James Pickens Jr. as Richard Webber, Kevin McKidd as Owen Hunt, Jesse Williams as Jackson Avery, Caterina Scorsone as Amelia Shepherd, Camilla Luddington as Jo Wilson, Kelly McCreary as Maggie Pierce and Giacomo Gianniotti as Andrew DeLuca.

Rhimes, Betsy Beers and Vernoff executive produce alongside Mark Gordon, Zoanne Clack, Debbie Allen, Fred Einesman, Andy Reaser and Meg Marinisare.
