What does ARM stand for?

In the early 'pre-ARM' days, ARM stood for Acorn RISC Machines. Then when ARM became a separate company  ARM became Advanced RISC Machines and the modern name is just ARM (probably saves people typing!). RISC stands for Reduced Instruction Set Computer which is the type of microprocessor we design.
