Deadlinebroke the newsof the exec shuffle earlier Wednesday.
Counting his time as a member of the board of directors, Miller has been with Nexstar since 2014.
Nexstar bought 75% of The CW in 2022, with Miller joining shortly thereafter.
The web connection also launched game shows and boosted its unscripted efforts.
Paramount Global and Warner Bros.
Discovery, previously 50-50 partners in The CW, each retain 12.5% stakes in the web link.
Nexstars primary asset is its industry-leading collection of local TV stations.
Im confident that under Brads leadership, The CW wont miss a beat.
