Dish Network just rolled out a beta version of a new Sling TV package, priced at $20 per month, that will include 21st Century Fox channels for the first time. The new Sling TV package also allows for three simultaneous streams, aimed at families with multiple viewers, and will contain Fox channels FX, regional sports networks and, in 17 markets initially, the Fox broadcast network. What it won’t include is channels from Disney, which continues to be part of the earlier, single-stream Sling TV bundle.

The Wall Street Journal reports that the earlier Sling TV bundle that includes Disney channels such as ESPN, ESPN2, ABC, Disney Channel and Freeform will continue to be sold, but limits users to a single stream.

In addition to Fox channels, the new multi-stream Sling TV bundle offers on-demand access to “Empire,” the full catalog of “The Simpsons” as well as content from AMC Networks, A&E Networks, HBO, Turner channels, Scripps Networks Interactive, EPIX, and Univision Communications. Also on Sling TV are Fox’s YES Network, which airs the Yankees, Fox Sports 1 and the line-up of NFL games on Fox broadcasting.

The YES Network might be appealing to Comcast subscribers in the Northeast, where a carriage dispute has knocked the channel off the lineup.

“Since launch, our customers have asked for more channels and multiple streams,” said Sling TV chief executive Roger Lynch, who adds that the Fox content and multi-stream service are “the first step in answering their requests.” Fox Networks Group chief executive Peter Rice said the new “affordable” package is “designed for a new and younger TV audience.”

The original Sling TV package, with the Disney channels, will continue to be available, but without the Fox channels; customers can buy both packages.
