Although modest about his own abilities and generous in his praise of other cricketers, Bradman was fully aware of the talents he possessed as a player; there is some evidence that he sought to influence his legacy. During the 1980s and 1990s, Bradman carefully selected the people to whom he gave interviews, assisting Michael Page, Roland Perry and Charles Williams, who all produced biographical works about him. Bradman also agreed to an extensive interview for ABC radio, broadcast as "Bradman: The Don Declares" in eight 55-minute episodes during 1988.
