tdgeek: You cannot regulate Sky, on what basis? Monopoly? Sky has a technical monopoly, but it is not in a position of control of the market. Others are free to join and compete with Sky. Others being similarly large operators globally.
As there is no infrastructure to build, there is freedom and ease to compete here.
If Sky had a true monopoly, that made it impossible for others to join and compete, you may then have a case for regulation. Unless Sky have bought all satellite rights and bandwidth to stop others entering, there is no case.
If say, FTA took the F1, RWC, etc from Sky, then who will pay for that? Will we get a subscription for TVNZ? Or 4 minutes of RWC then 4 minutes of ads as happens in some high interest content?
There is infrastructure to build depending on what technology was chosen. You either have to get access to a satellite, or you have to build UHF broadcast towers. The current ones don't currently cover the entire country. You also have to have either a lot of capital to set it up and advertise, until you get a large enough customer base. You also have to pay for content, and get the exclusive deals for the premium content. It is a huge undertaking with huge costs and I can't see anyone starting one up. The cost is the barrier to entry, as is our relativity small population. Look what happened to the mobile market once it became regulated, we got 2 degrees come in.
