They are, of course, YouTube at 17% and Netflix at 33%. But what this shows, more than anything, is how far other services are lagging behind. The major broadcasters have been criminal with their head in the sand strategies - ABC is taking some shows online a decade after pioneering broadcaster in the UK and elsewhere did so.
But what about Hulu and Amazon (OK, Netflix does use the Amazon network so they make a small cut) ? And Microsoft and Apple ?
As with most markets these days, one or two players get to the tipping point and the rest is history. I feel that we've reached one of those points in the TV industry.
