On the day that ABC is about to unveil her latest drama series, “Scandal” and “Grey’s Anatomy” creator Shonda Rhimes has set a long-term extension of her overall deal with ABC Studios.

Deal calls for her Shondaland banner to remain with ABC Studios through May 2018. ABC today will unveil its 2014-15 schedule to advertisers in Gotham, and a centerpiece of that presentation is expected to be Shondaland’s “How to Get Away with Murder.” The series was was created by “Grey’s Anatomy” vet Peter Nowalk and exec produced by Rhimes.

Rhimes’ deal extension has been a long time in the works, given the amount of business she has in play at the Alphabet and her status as an uber-showrunner. “Scandal” blossomed into a bona fide hit for ABC this past season, and “Grey’s Anatomy” remains a Thursday workhorse for the network.

Betsy Beers runs Shondaland with Rhimes.

Rhimes is repped by ICM Partners.
