Rick Adams

Oh, it grew significantly.

The article notes that by 1996, Randi received financial backing from an internet entrepreneur named Rick Adams.

Mm-hmm.

The prize ballooned.

Then, during the late 1980s, he was part of a television program where the prize was increased to $100,000, although the rest of the money was supplied by the broadcasting company.

Eventually, thanks to a donation by internet entrepreneur Rick Adams, Randi permanently increased the prize to a million dollars.

Ever since the 1960s, around 1,000 people have tried taking Randi up on his offer.

According to the official guidelines, the exact circumstances of the tests were agreed upon in advance by both parties, and afterwards could not be changed no matter what.
