We had both the Sling Orange and Blue basic. One of SIL's who hates the NFL gave us a great heads up. Sling Blue doesn't carry any ESPN or Disney channels.
We don't watch ESPN or Disney, however, they were getting money from us by subscribing to Sling Orange.
I got that info from my SIL yesterday. A few minutes later I had cancelled Sling Orange. So ESPN and Disney get zero money from my Sling Blue monthly subscription payment.
What Is Sling Blue?:
Sling Blue costs $25 per month and gives you access to 43 live channels. However, Blue does not include every Orange channel by default; theres no Disney and no ESPN, for starters.
