 Defunct computer companies of the United Kingdom

The United Kingdom has had a number of notable computer companies that are now defunct. Here are some examples: 1. **Acorn Computers**: Founded in 1978 and well-known for developing the BBC Micro, Acorn played a significant role in the home computer revolution in the 1980s. The company eventually shifted its focus to ARM technology, which it still licenses today, but it ceased trading as a computer manufacturer in the early 1990s.
