Analysis of information sources in references of the Wikipedia article "David Frost" in English language version.
The tournament was dramatic enough thanks to Fischer's antics, but telephone conversation on 3 July 1972, capturing British journalist David Frost asking Kissinger to persuade the grandmaster to attend the championship adds more to the story. Kissinger had an intellectual interest in chess, and the Spassky-Fischer head-to-head alone would have likely piqued his interest in the match, but Frost wanted Kissinger to get involved to ensure Fischer's participation.
In 1968 he set up his own company, David Paradine Productions, and by 1969 his salary was rumoured to be £500,000.
