This is the first computer. Charles Babbage, an English mechanical engineer and polymath, created the original computer in 1822. The first electronic computer ENIAC weighed more than 27 tons and took up 1800 square feet. It was very bulky and not commonly used.

This is the Turing machine. It was invented by Alan Turing in 1936. It was used in WWII to have the allies crack the German code. It was a main factor in the allies ability to win the war. It also known as the basis for most modern computers.

This is the UNIVAC invented in 1946, and the first commercial computer for sale. 46 machines were built, for about $1 million each. The UNIVAC I machines were small -- about the size of a one-car garage. UNIVAC I came to the public's attention in 1952, when CBS used one to predict the outcome of the presidential election.

In 1976, Steve Wozniak invented the Apple I, and Steve Jobs convinced him to sell it. It is the first single circuit board computer, and came assembled. At the time, computers did not come assembled, and consisted of multiple circuit boards. The wholesale price of the computer was $500. The retail price was $666.66.

This is an advertisement for an old Apple computer.

The laptop was invented by Adam Osborne in 1981. It was called ''Osborne 1'' and cost $1,795. It came bundled with $1,500 worth of programs. It had a tiny computer screen built into it. It was invented by Osborne Computers. It was revolutionary because now computers didn't have to stay in one place.

The newest Macbook Pro came out in 2017. It costs $4,299. It's lighter, and faster, with color, and a touch screen bar. It has better color, picture, and much more.

Right now more than 2 billion people in the world own computers. There's always so much buzz whenever there'a new computer released, because everybody wants the latest model. This product will continue changing and developing to fit the future and the needs. I predict computers getting smaller and thinner to carry around, touch screens, and more. There's so much I can't even imagine but for something with so many options for change, computers will definitely continue to change and be used in the future.
