In a few years everyone will have an apple tv or similar device and we'll be watching rugby games (and everything else) through some app or another.
I think these recently announced big AFL and NRL deals with FTA networks may be the last of their kind. You don't see much sport on FTA in places like America and the UK and I can't imagine it'll stay that way here. The FTA networks don't make any money from these deals, they're just desperately trying to maintain relevance. They won't be able to afford it soon.
Not at all.
The NFL is on FTA in local markets i.e. if you're in New York all New York based team games are live on FTA as long as the game is sold out (which it always is in NY)
Apart from that Fox (FTA) and CBS (FTA) have 3 live national games between them on Sunday afternoons. NBC (FTA) has the live Sunday night game. CBS also have some Thursday night games. The only "premium" broadcast is Monday Night Football on ESPN and until last year every playoff game was on FTA, ESPN get one game out of 11 now. ESPN isn't even that premium like a Fox Sports Australia, it's on basic cable and available to most. "Premium" NFL broadcasting is Direct TV season ticket which is just access to all games but you would be a very hardcore supporter (or someone transplanted from your local team who want to watch every game) to need that. The NFL is mostly about selling advertising, not subscriptions.
The NBA has their Finals on ABC and live weekly games on Sundays.
The MLB also has live national games weekly on Fox with the playoffs and World Series also there. Apart from that again it's on basic cable. The NHL has FTA agreements with NBC. With golf all the Majors are on FTA with many other events FTA. College football wise if you flick on FTA channels on a Saturday you'll see games across all the FTA networks.
ESPN do have more and more events like the US Open (Tennis), College Football playoffs and a few more that they've taken off FTA but FTA still has most of the big stuff and a huge amount of live FTA content.
The UK is definitely dwindling but the UK has always been a bit different. As the BBC had such a big hold there sport didn't commercialise as it has in Australia and the US on FTA, that allowed Sky to step in. With the BBC under funding threats FTA sport has gone down but there is still a lot of it.
In places like Australia and the US I can only see the form changing. Apple TV will just stream these live events and these channels will pick up the ad $s.
