IBM Computer History: PS/2 - Personal System/2: IBM’s Second Generation PC Family 1987. Three IBM commercial spots originally shown in 1988 on CBS "A Christmas Carol" TV special. Includes the IBM “PS/2 It!” ad song. A short AS/400 promo is included also. The IBM PS/2 was announced in April 1987, and over 20 models were eventually made. Most featured IBM's Micro Channel Architecture ("MCA") bus, a proprietary 32 and 16 bit standard aimed at recapturing the PC market. Several early low-end PS/2 models used the ISA (Industry Standard Architecture) 16-bit bus based on Intel's 286 chip which had been widely cloned by non-IBM vendors. Various models of PS/2 were made including desktops, towers, portables, laptops, notebooks and large file servers. IBM's OS/2 operating system was also released the same year (1987.)

IBM's PS/2 product family was eventually phased out in 1995. IBM sold its PC business to the Chinese firm Lenovo Group in 2005, who started selling "Lenovo" branded PCs in 2006.
