Byte magazine Creative Computing Apple II PET 2001 TRS-80 microcomputers personal computer
Over the next seven years, the phrase had gained enough recognition that Byte magazine referred to its readers in its first edition as "[in] the personal computing field", and Creative Computing defined the personal computer as a "non-(time)shared system containing sufficient processing power and storage capabilities to satisfy the needs of an individual user." In 1977, three new pre-assembled small computers hit the markets which Byte would refer to as the "1977 Trinity" of personal computing. The Apple II and the PET 2001 were advertised as personal computers, while the TRS-80 was described as a microcomputer used for household tasks including "personal financial management". By 1979, over half a million microcomputers were sold and the youth of the day had a new concept of the personal computer.
