When Picture Post folded, Sir Edward Hulton sold the archive collection to the BBC in 1957. It was incorporated into the Radio Times photo archive, and the BBC expanded the collection further with the purchase of the photo archives of the Daily Express and Evening Standard newspapers. Eventually, the BBC disposed of its photo archive and the BBC Hulton Picture Library was sold on once more, this time to Brian Deutsch, in 1988.
In 1996, the Hulton Picture Collection was bought by Getty Images for £8.6 million. Getty now owns the rights to some 15 million photographs from the British press archives dating back to the 19th century.
