Shonda Rhimes’ Grey’s Anatomy continues to be in a league of its own. A heavily serialized drama, a genre that often commands limited-run seasons of 13-18 episodes a year –strategy employed by such high-profile dramas as NBC’s This Is Us, Fox’s Empire and ABC/Shondaland’s How To Get Away With Murder — Grey’s has been able to deliver suppressed seasons for most of its long run while remaining a ratings stalwart. Besides its original midseason run, 12 of Grey’s 13 subsequent seasons have consisted of 24 or 25 episodes each.

As a result, Grey’s Anatomy, now in its 14th season, is about to cross the 300 episode mark.

The Kapital Entertainment-produced, Sarah Dunn-created American Housewife, a promising newcomer last season when it produced 23 episodes, has made a successful move to its high-profile new time slot this season, Wednesdays at 9:30 PM, behind Modern Family. Meanwhile, Kenya Barris’ black-ish, has done solid business holding up Tuesdays as new 9 PM anchor. Now in its fourth season, black-ish has had orders for extra two episodes every year, churning out 24 episodes a season.
