CW and Nexstar have set a long-term renewal of their affiliation agreement, securing the network’s broadcast distribution in 37 markets with the nation’s largest TV station owner.

The deal covers Nexstar’s WPIX-TV New York and KTLA-TV Los Angeles, in addition to other top 10 markets such as KDAF-TV Dallas and KIAH-TV Houston. In all, Nexstar’s CW affiliates reach more than 38 million TV households representing about 31% of all U.S. TV homes. The renewal comes on the heels of CW unveiling a plan to expand to a full seven-night primetime schedule for the first time in the network’s nearly 15-year history.

“As the nation’s largest CW affiliate group, Nexstar is very pleased to extend its longstanding relationship with the network,” said Tom Carter, Nexstar’s president, chief operating officer and chief financial officer. “The CW’s line-up of prime-time entertainment shows, coupled with Nexstar’s highly-rated local news and other market-centric programming enables us to deliver great content to millions of viewers and exceptional value to our advertisers.”

Nexstar is the successor owner of Tribune Broadcasting, the station group that formed the core of CW predecessor the WB Network. Tribune was a partner with Warner Bros. in the venture from its 1993 origins, and it hung in through the network’s rocky early years after its on-air launch in 1995. Tribune Co. has been through several rounds of M&A and owners, including the most recent $4.1 billion sale in 2019 to Texas-based Nexstar Media Group, but the WB and now CW affiliation has remained constant. CW has has a solid track record in recent years with buzzy new young adult-centered dramas including “Riverdale,” “The Flash” and “Batwoman.”

“We are pleased to extend our valued partnership, through a multi-year agreement, with our largest station group, Nexstar,” said Betty Ellen Berlamino, CW’s executive VP of distribution. “The linear broadcast model remains the backbone of our business model and vitally important as it gives us the scale and local reach that distinguishes us in today’s marketplace as the original multiplatform network.”
