The IBM personal computer model 5150

On August 12, 1981 IBM announced the release of its Personal Computer, identified as model 5150. This expression, as well as microcomputers and home computers, had already been used before so you could say that actually the first personal computer was the Xerox Alto in 1973 or even the Olivetti Programma 101 about a decade earlier. The success of the IBM PC however was such that within a short time the expression personal computers started identifying a model compatible with the IBM one.

Google confirmed that it bought over a thousand patents from IBM but details were not revealed. Some sources report that the patents bought are 1,029, according to other sources they’re 1,030, either way the amount paid by Google wasn’t disclosed. The important fact is that the acquired patents cover technologies related to hardware and in particular the production of microprocessors and memories but also Internet-related technologies.
