In 1999, the Pentagon banned sales of Apple's 400 MHz Power Mac G4 in 50 countries, marking the first time a personal computer was classified as a weapon. Steve Jobs turned the restriction into a marketing coup, framing the ban as proof of the machine's extraordinary power.

The export control, imposed under Cold War-era regulations, labeled the G4 a 'supercomputer' due to its processing capabilities. Jobs famously declared that 'for the first time in history a personal computer has been classified as a weapon,' using the designation to burnish Apple's performance credentials.

The ban affected only the highest-end 400 MHz model, leaving lower-specced versions available internationally. Apple splashed the 'weapon' designation in advertisements, turning a regulatory hurdle into a badge of honor that boosted the G4's mystique among enthusiasts.

This historical episode resonates amid today's tech export battles, particularly US restrictions on advanced chips to China. It illustrates how companies can reframe regulatory setbacks as brand-building opportunities, though the scale and stakes of modern export controls dwarf those of 1999.

Some critics argue Jobs' marketing glossed over the real-world implications of restricted access, which limited high-performance computing in affected regions. The episode remains a case study in turning adversity into advantage.
