It just surprised me. I had to listen to Fox News on the Sirius XM Radio. Sling seems like its run a lot better then Sirius XM Radio and thus would be a no brainer to sign a contract with to get Fox News on the Sling system.
MSNBC and CNBC are in the World News Extra ($5) package, which is where one would assume to find Fox News at some point. I find it surprising in the sense that Sling TV carries all the other major Fox channels, including some of their sports channels, which are usually much harder to negotiate. And it's not like Fox News is a niche channel like the Fox Business News channel; it's the top-rated cable news channel. There has to be some reason other than Sling just hasn't gotten around to lining it up yet.
