VIDEO : 'Grey's Anatomy' Makes History With 332nd Episode

With Thursday night's airing of its 332nd episode, the ABC series became the longest-running medical drama on television. Titled "We Didn't Start the Fire," the episode centered on the character of Jackson (played by Jesse Williams) throwing a party to celebrate the surgery of his mother, Catherine (Debbie Allen). To celebrate, Allen, who also has directed some episodes, posted a video with her and some of her co-stars debating if they were a "TV show" or a "medical drama." A post shared by Debbie Allen (@therealdebbieallen) on Feb 28, 2019 at 6:41am PST "Accomplishing something history-making is an excellent way to close out #BlackHistoryMonth," Rhimes tweeted.
