The CW, co-owned by CBS, is not currently a part of the live streaming deal, and it’s not clear if that will change before the service launches.
Hulu and The CW were partnered for five years, but that flipped when Netflix put their money on the table for exclusivity on current seasons of hit shows.
There’s a chance that live streaming hits a different area of the contracts than post-season streaming, giving Hulu and Netflix the rare chance to work together on something, but it probably isn’t too likely.
There is a caveat here, for those who read “CBS-owned networks” and automatically assumed it meant all of them, but it looks like CBS Sports and Pop are the only others presently included.
