When the IBM PC made its debut in 1981, Norton was among the first to buy one. After he was laid off during an aerospace industry cutback, he took up microcomputer programming to make ends meet. One day he accidentally deleted a file. Rather than re-enter the data, as most would have, he decided to write a program to recover the information from the disk. His friends were delighted with the program and he developed a group of utility programs that he sold – one at a time – to user groups. In 1982, he founded Peter Norton Computing with $30,000 and an IBM computer.
