Microprocessors as a whole were a result of the US military industrial complex. The first large scale use of integrated circuits was the Minuteman II ballistic missile guidance system. The lineage that leads to the modern smartphone starts with Texas Instruments winning the contract for that military guidance system (first as a subcontractor to North American, then fully on their own).
Similarly, the first production use of a charge-coupled device for digital camera technology was the KH-11 spy satellite.
