The as-yet-untitled Seattle-set firefighter series is another example of how Grey's Anatomy creator, Shonda Rhimes is completely dominating the TV drama landscape. Medical drama Grey's Anatomy is in its 13th season and is still bringing home the ratings, consistently hitting number one in the US in its Thursday night timeslot. Following Grey's, huge US network ABC then fills the rest of must-watch Thursday night TV with two more Rhimes-produced shows, Scandal and How to Get Away With Murder. It's fair to say Rhimes is comfortable creating a killer scripted drama.

In a statement to The Hollywood Reporter, ABC Entertainment president Channing Dungey said, "No one can interweave the jeopardy firefighters face in the line of duty with the drama in their personal lives quite like Shonda, and Grey's signature Seattle setting is the perfect backdrop for this exciting spin-off."  No news on a launch date but the first episode of the series is rumoured to be weaved into a Grey's Anatomy episode, with the Grey's season 13 finale the likely contender (it apparently features an explosion at Seattle Grace Hospital).

The series will be written by Stacy McKee a Grey's Anatomy alumni, and produced by ABC Studios and Rhimes' production company, Shondaland. The firefighter spin-off marks the second spin-off from Grey's Anatomy, the first was Private Practice which ran for six seasons.
