The last three decades of the twentieth century saw a large increase of membership of the Trust from 160,000 in 1968 to over two million by the time of its centenary in 1995, much of it down to the Trust's employment of a director of public relations, as recommended by the Benson report, and regional information officers. Starting in the 1970s, tea rooms and souvenir shops were opened in Trust properties and in 1984 a company was set up to operate the trading activities. Programmes of events, including plays and concerts, and educational activities were organised at Trust properties. The Trust appointed its first female chairman, Dame Jennifer Jenkins, in 1986.
