There are reports today that that ITV are in discussions to make their non public service channels (ITV2/+1, ITV3/+1 & ITV4/+1) part of the Sky subscription service.
With advertsing revenues down, ITV can essentially mak money from a proportion of the sky subscription payments.
this is just early discussions.
it is not confirmed.
it will mean that you will only be able to view ITV2,3,4 with a sky subscription card.
and will mean that “rebroadcasters” in spain will have to remove these channels as they are “encrypted” channels, just like they have with the many other sky channels.
