Apple is currently the most valuable technology company in the world, and it all started in the garage of Steve Jobs’ parents. In 1976, Steve Jobs and Steve Wozniak, 21 and 26 respectively, took over the garage and handbuilt 50 computers in 30 days for a local retailer, selling them at $500 a piece. From then on, there was no stopping them. Address: 2066 Crist Dr, Los Altos, California
