In late 1971, HP faced economic challenges and decided to try something new with the HP-35 scientific calculator. They marketed it directly to consumers through magazine ads, breaking away from traditional methods. The project faced various engineering challenges and pushed the limits of semiconductor fabrication. Despite doubts from experts, the HP-35 was a massive success, selling over 100,000 units in the first year and revolutionizing the engineering profession. The unique design, distribution strategy, and innovative technology behind the HP-35 made it a game-changer in the consumer electronics industry.
