input: Stirling refers to Grant as "one of the shrewdest businessmen ever to operate in Hollywood". His long-term friendship with Howard Hughes from the 1930s onward saw him invited into the most glamorous circles in Hollywood and their lavish parties. Biographers Morecambe and Stirling state that Hughes played a major role in the development of Grant's business interests, so that by 1939, he was "already an astute operator with various commercial interests". Scott also played a role, encouraging Grant to invest his money in shares, making him a wealthy man by the end of the 1930s. In the 1940s, Grant and Barbara Hutton invested heavily in real estate development in Acapulco at a time when it was little more than a fishing village, and teamed with Richard Widmark, Roy Rogers, and Red Skelton to buy a hotel there. Behind his business interests was a particularly intelligent mind, to the point that his friend David Niven once said: "Before computers went into general release, Cary had one in his brain". Film critic David Thomson believes that Grant's intelligence came across on screen, and stated that "no one else looked so good and so intelligent at the same time". After Grant retired from the screen, he became more active in business. He accepted a position on the board of directors at Faberge. This position was not honorary, as some had assumed; Grant regularly attended meetings and travelled internationally to support them. His pay was modest in comparison to the millions of his film career, a salary of a reported $15,000 a year. Such was Grant's influence on the company that George Barrie once claimed that Grant had played a role in the growth of the firm to annual revenues of about $50 million in 1968, a growth of nearly 80% since the inaugural year in 1964. The position also permitted use of a private plane, which Grant could use to fly to see his daughter wherever her mother, Dyan Cannon, was working. In 1975, Grant was an appointed director of MGM. In 1980, he sat on the board of MGM Films and MGM Grand Hotels following the division of the parent company. He played an active role in the promotion of MGM Grand Hotel in Las Vegas when opened in 1973, and he continued to promote the city throughout the 1970s. When Allan Warren met Grant for a photo shoot that year he noticed how tired Grant looked, and his "slightly melancholic air". Grant later joined the boards of Hollywood Park, the Academy of Magical Arts (The Magic Castle, Hollywood, California), and Western Airlines (acquired by Delta Air Lines in 1987).

Question: David Paradine Frost was born in Tenterden, Kent, on 7 April 1939, the son of a Methodist minister of Huguenot descent, the Rev. Wilfred John "W. J." Paradine Frost, and his wife, Mona (Aldrich); he had two elder sisters. While living in Gillingham, Kent, he was taught in the Bible class of the Sunday school at his father's church (Byron Road Methodist) by David Gilmore Harvey, and subsequently started training as a Methodist local preacher, which he did not complete. Frost attended Barnsole Road Primary School in Gillingham, St Hugh's School, Woodhall Spa, Gillingham Grammar School and finally - while residing in Raunds - Wellingborough Grammar School. Throughout his school years he was an avid football and cricket player, and was offered a contract with Nottingham Forest F.C.

Frost was one of the "Famous Five" who launched TV-am in February 1983 but, like LWT in the late 1960s, the station began with an unsustainable "highbrow" approach. Frost remained a presenter after restructuring. Frost on Sunday began in September 1983 and continued until the station lost its franchise at the end of 1992. Frost had been part of an unsuccessful consortium, CPV-TV, with Richard Branson and other interests, which had attempted to acquire three ITV contractor franchises prior to the changes made by the Independent Television Commission in 1991. After transferring from ITV, his Sunday morning interview programme Breakfast with Frost ran on the BBC from January 1993 until 29 May 2005. For a time it ran on BSB before moving to BBC 1. Frost hosted Through the Keyhole, which ran on several UK channels from 1987 until 2008 and also featured Loyd Grossman. Produced by his own production company, the programme was first shown in prime time and on daytime television in its later years. Frost worked for Al Jazeera English, presenting a live weekly hour-long current affairs programme, Frost Over The World, which started when the network launched in November 2006. The programme regularly made headlines with interviewees such as Tony Blair, President Omar al-Bashir of Sudan, Prime Minister Benazir Bhutto of Pakistan and President Daniel Ortega of Nicaragua. The programme was produced by the former Question Time editor and Independent on Sunday journalist Charlie Courtauld. Frost was one of the first to interview the man who authored the Fatwa on Terrorism, Muhammad Tahir-ul-Qadri. During his career as a broadcaster Frost became one of Concorde's most frequent fliers, having flown between London and New York an average of 20 times per year for 20 years. In 2007, Frost hosted a discussion with Libya's leader Muammar Gaddafi as part of the Monitor Group's involvement in the country. In June 2010, Frost presented Frost on Satire, an hour-long BBC Four documentary looking at the history of television satire.
