The original Apple I computer was invented by Steve Wozniak and Steve Jobs and was first released on April 1, 1976. The Apple I was the very first computer to be built with a single circuit board and was sold for $666.66.
Although Apple is one of the most famous names in computers, it wasn't always that way. In fact, Wozniak and Jobs only sold around 200 of the original Apple I model during their first year in business. The two of them had to assemble each one by hand.
The next year, the two founders released the improved Apple II, which went on to revolutionize the computer market and paved the way for Apple to grow into one of the largest and most successful computer companies in the world.
Both Wozniak and Jobs were computer hobbyists who suddenly released that the rise in personal computers meant that the price of computer parts was low enough for them to buy the parts separately and build their own computers. This is exactly what they then set out to do, with the result being the original Apple I. The Apple I eventually made Steve Jobs and Apple Computers into a household name despite its initial limited success.
