Producer or distributor?

Hello, I have a question. The credits of one of the episodes of the series I'm watching say: Produced by PROMETHEUS ENTERTAINMENT For HISTORY. © 2013 A&E Television Networks, LLC. All Rights Reserved. How can this be assigned: 1) Produced by Prometheus Entertainment; Distributors: HISTORY and A&E Television Networks, 2) Produced by Prometheus Entertainment: for History; Distributor: A&E Television Networks, 3) or something else? Thank you for your answer. Rafał
