Grey's Anatomy is about to steal a record from another beloved medical drama!
The Shonda Rhimes drama is poised to overtake ER as the longest-running medical drama of all time.
ER ran for 15 seasons with a total of 331 episodes. Grey's Anatomy is in its 15th season and it will reach ER's record after the winter break.
According to TVLine, the production team has a cheeky surprise in mind for fans. The record-shattering episode will supposedly feature zero medical storylines.
Rhimes took the approaching milestone as an opportunity to reflect on what the show has accomplished in that time, calling it a "once in a lifetime experience."
"I am still a little in shock to discover @GreysABC is about to become the longest running medical drama ever," she wrote on Twitter. "Best crew, best fans, best cast -- once in a lifetime experience. #GreysAnatomy"
The show's beloved lead, Ellen Pompeo, seconded her opinion. "What she said," Pompeo chimed in in a reply tweet.
The long-running ABC medical drama will resolve the cliffhanger-heavy season 15 fall finale with a new episode on Thursday, Jan. 17 at 8 p.m. ET.
Not everything will be as fans expect, though. ABC is shaking up the network's TGIT (Thank God It's Thursday) programming night, as new episodes of ABC series A Million Little Things will be taking over Station 19's post Grey's timeslot for the remainder of its first season run.
Jan. 17 will also mark the return of ABC's Shonda Rhimes-produced drama How to Get Away With Murder at 10 p.m. ET.
Grey's Anatomy's firefighter spinoff Station 19 will return for the second half of Season 2 on March 7, returning to its 9 p.m. timeslot, followed by the Season 2 premiere of Shondaland drama, For The People at 10 p.m. That date will mark the return of the TGIT lineup.
There will be no shortage of Grey's Anatomy episodes in the upcoming spring part of the season since the series was granted a three episode extension.
The 25-episode season will be its second longest of all time and its longest in a decade. Due to the extension and the continued strong ratings, it is likely Grey's Anatomy will crush ER's record by more than just a few episodes. The series is expected to get a further season order.
