Soup - 2007 article? WEHI wasn't a big rating hit at all. They received "outstanding" responses, but no mention of whether there were more than 2 responses total.
WEHI was required to pay the prize winning team the $1,000,000 30 days after the final episode.
Looks like, as of 2009, WEHI still hasn't paid the winning team or many past prize winners of other contests.
No wonder there are so many judgement liens against WEHI.
