NBCUniversal has entered into what’s being described as a “mega deal” with one of the most successful creators of television programming. Deadline.com reports that Dick Wolf, the creator behind two hit NBC franchises in the “Law & Order” and “Chicago” dramas, is extending his deal after 30 years with Universal Television.

“The five-year pact with NBCUniversal, which will keep Wolf at the company through 2020, came after months of negotiations, which is understandable given Wolf’s stature of an uber producer with four drama series on NBC — three installments of the ‘Chicago’ franchise, with a possible fourth on the way, and ‘Law & Order: SVU’ — an upcoming ‘Law & Order’ reality spinoff on the network, ‘Law & Order: You the Jury,’ as well as a slew of unscripted cable series,” Deadline reports.

In connection with the new deal, “Law & Order: SVU” was renewed for an 18th season and “Chicago Med” was picked up for season two. The renewals follow previous pickups for “Chicago Fire” and “Chicago PD.”
