Bit annoyed about Spark Sport snapping up the F1 and not even having their service up and running with mere days to go until the first Grand Prix. Looks like they've chucked it on TVNZ Duke as a sort of, 'sorry, we're not quite up and running yet but here it is for free.'
If they have the site up and running before Friday then fair enough, but otherwise it's a big fail.
Also appears that they won't be launching with on-demand availability, which will only be available at a 'later date.'
