To be fair Sky have had SL and NRL as a package when RL here moved to the summer. Maybe because they had both they didn't feature or value NRL as much as Premiers Sports do now.
In the days when it was split between Sky and the BBC it usually felt like an underling sport with Sky majoring on soccer and the BBC who treated it like a novelty northern game they could use when there was no Union on.
BBC still have the Challenge Cup coverage and to be fair, Sky brought the production values and camera work to higher levels, lifting the bar for 'auntie' to follow.
The advantage of PSTV is that they do feature Rugby League as a key part of their portfolio. All they need now is Super League to join them and we'd have a superb value for money package that did justice to our great game.
