The BBC is almost underselling ARM's significance here. ARM make almost all of the processors in your phone, including the CPU and GPU. They design the processors and interconnection chipset architecture, then Qualcomm and Samsung license the designs to build mobile devices. Almost all of our phones each have at least 7 ARM processors in them.

It's very sad that ARM is becoming a publicly traded company and yet another Wall St pawn. And all of this was triggered by Brexit, up until then it was privately owned by its founders.
