One of the great business institutions of the modern era is the BBC which is now 100 years old. The authors explored letters and memoranda in the BBC’s Written Archives at Caversham, which revealed much about the business tactics of those in charge of the BBC during the pre-Second World War era, and how they used the power of their monopoly to their own ends. A new market of broadcasting magazines sprang up around the radio broadcasts, creating an inter-dependency between the two media. The BBC soon launched its own magazines, and from then on, the BBC’s interactions with the press media were complex, reflecting an uncomfortable blend of symbiosis and threat. Episodes between the press owners and the BBC have been uncovered, about which there has been little previous investigation, and unexpected patterns of behaviour have emerged. This archival research, using narrative history, is based upon original letters, memoranda and handwritten messages that were archived for posterity, and which report upon the actual thoughts and views of those involved at the time, revealing unexpected intrigue and machinations.
