'Grey's Anatomy' fans were in for a walk down memory lane with a special 'Throwback Thursday', with two fan-favorite episodes, Season 2, Episode 16 'It's the End of the World' and Season 2, Episode 17 'As We Know It', back to back. But while looking back is always fun, it's looking forward to more storylines with their favorite characters that get fans excited. Fans of 'Grey's Anatomy' fortunately have a lot more of those to look forward to, with 'Grey's Anatomy' now renewed for a new season.

Season 17 was one of the most emotional seasons yet, not just for fans but also for the show creators, who were unclear themselves if the show would be coming to an end with Season 17. But for fans of 'Grey's Anatomy' fortunately, there is now plenty more medical drama to look forward to at Grey Sloan Memorial, with the show now renewed for another season. Krista Vernoff the showrunner of 'Grey's Anatomy' in a statement said, "The writers, directors, casts and crews of Grey’s Anatomy and Station 19 worked so hard to bring these shows to life this past season. Keeping each other safe on set while paying tribute to the front-line heroes and first responders has been a challenge and a privilege. I’ve been truly blown away — particularly by our tireless crews — as they reinvented the TV-making wheel. Thank you to ABC and ABC Signature for the support and extraordinary partnership through this unprecedented season. We are so grateful for the opportunity to tell more stories.” Also returning for its fifth season is 'Grey’s Anatomy' spin-off, 'Station 19', which will be back for its fifth season.
