Text:
The British Radio Valve Manufacturers' Association (BVA) was established in July 1926 and was a registered trade union. It had been preceded by the Valve Manufacturers' Association, which had established a 'Memorandum of Sales Plan'. This agreement, which was signed by the seven major British valve manufacturers, secured a uniform practice in the sale of radio valves for broadcasting purposes in the UK. Practical examples included similar discounts and sales conditions, and were considered a form of restrictive practice. This association continued into the 1950s.
