Campaigning directly to the people became commonplace. Several 20th-century prime ministers, such as David Lloyd George and Winston Churchill, were famous for their oratorical skills. After the introduction of radio, motion pictures, television, and the internet, many used these technologies to project their public image and address the nation. Stanley Baldwin, a master of the radio broadcast in the 1920s and 1930s, reached a national audience in his talks filled with homely advice and simple expressions of national pride. Churchill also used the radio to great effect, inspiring, reassuring and informing the people with his speeches during the Second World War. Two recent prime ministers, Margaret Thatcher and Tony Blair (who both spent a decade or more as Prime Minister), achieved celebrity status like rock stars, but have been criticised for their more 'presidential' style of leadership. According to Anthony King, "The props in Blair's theatre of celebrity included ... his guitar, his casual clothes ... footballs bounced skilfully off the top of his head ... carefully choreographed speeches and performances at Labour Party conferences."
