Sinclair Broadcast Group, America’s largest owner of local TV stations, will shortly launch a new ad-supported streaming service called Stirr that will incorporate local news from Sinclair TV stations, conservative political commentary, and syndicated entertainment shows and movies.

There is no word yet exactly when the service will launch or whether a subscription fee will be charged, but Sinclair intends to use the power of its large stable of local television stations to heavily promote the service to consumers.

Stirr will be based in Los Angeles and Seattle. The Sinclair-owned Tennis Channel is providing technical and operational assistance to get the service launched in time to compete with the forthcoming subscription service from Fox News Channel – Fox Nation, which is targeting a similar audience.

Sinclair stations license a significant amount of syndicated programming. Sinclair hopes this will help convince content owners to license their shows for streaming on the forthcoming Stirr app.

Sinclair will also be able to offer subscribers 24/7 access to local newscasts and news clips, as well as content produced at its Baltimore headquarters. Much of that corporate-produced content is political commentary that has historically been very supportive of President Donald Trump and the Republican Party, and very critical of the Obama Administration and Democrats generally. Commentators like Mark Hyman and Boris Epshteyn, a former Trump campaign manager, are required to be carried on Sinclair owned stations.
