I think it was more that the British had a useful purpose in mind for it, whereas the Dutch didn't care one whit about it, than he popularised it. Australian history seems to teach that he was the first guy to ever come across both Australia and New Zealand, raising the rather interesting question of how Tasmania and New Zealand received their names.I think at least in one sense he did discover it insofar as he popularised it. Abel Tasman's rutters weren't well known outside the Netherlands and to the best of my knoweldge weren't released into the public domain until considerably later.
