"subscribers" mean.....that for example you have DirecTv, Comcast or that you have subscribed to a certain package ?

It's like WatchESPN which often prompts you, at least the first time, for which cable system you use and then asks you to sign on with it. I've noticed in my present setup, it detects that I use Comcast for my internet, so it does the initial check automatically.

Namely, that if you have a cable provider (say, Comcast) that it will allow one to access whatever ESPN platform is being used to run these ACC Network?

Would sincerely hope so because we Comcasters already pay these sports usage fee on our Comcast bill.

A couple of games this year, a few more next season,etc. The cable
companies must be getting a piece of the ESPN+ pie for carriage and
will be only too happy to accommodate ESPN. Then they will raise
the consumer price to 9.95 a month for ESPN+.

There will be a bunch of content still on WatchESPN (or ESPN3 or whatever it's called now). Whether they will take some of the content that is normally on there and put it on ESPN+ or just add stuff to put on ESPN+, it's hard to say.

I think the ESPN+ might be more for the people who don't have cable, so that they can get access (and ESPN can get money from them, too).

but the issue is the same. If they continue with the past process, it'll be OK for me...and for you.
