When was the first computer sold to the public?

The birth of the computer age is often attributed to the invention of the first electronic general-purpose computer, the ENIAC, in 1946. However, the ENIAC was a massive machine weighing about 30 tons and was primarily used for scientific and military purposes. It was not until a few years later that the first computer was sold to the public.

**The first computer sold to the public was the UNIVAC I, in 1951**.

The UNIVAC I, short for Universal Automatic Computer, was developed by J. Presper Eckert and John Mauchly, the same engineers behind the ENIAC. The UNIVAC I was significantly smaller and more practical than its predecessor, making it accessible for commercial use. This groundbreaking computer marked a new era in computing history, as it opened the door for other companies to venture into the computer market.
