We were impressed (but not surprised) when Grey’s Anatomy celebrated its tenth season, and when we got word that Ellen Pompeo (Meredith Grey) and Patrick Dempsey (Derek Shepherd) signed on for Seasons 11 and 12, we were super thrilled that our favorite show will live on for at least two more years. Yay!

We’ve got our own ideas on why the show’s lasted so long (and a lot of them revolve around the hottest doctors on television), but what else makes a TV show last over a decade? Sandra Oh (Cristina Yang) recently shared her insights on what’s made Grey’s last in an interview with On The Red Carpet.

And Sandra’s reasoning is simple: There’s no other show on TV like it.

“There aren’t a million of these shows, that’s why we’ve lasted as long as we have,” Sandra said. “10 years ago, there was a core group of characters who seemed to have just struck a chord, not only with people in America but internationally.”

So true — we couldn’t imagine Grey’s starring any other actors but the cast we’ve come to know and love, especially the core intern group — Ellen, Sandra, Justin Chambers (Alex Karev), and the surgeons who are no more, Katherine Heigl (Izzie Stevens) and T.R. Knight (George O’Malley).

“As that core family has changed and family members have come on, we’ve picked the right people and paired them up with the right people to continue that kind of loyalty with the characters,” Sandra added.

What do you think is responsible for making Grey’s last so long? Sound off below!
