ThinkPad
business computers and tablets series by Lenovo
ThinkPad is a line of business-oriented laptop and tablet computers produced since 1992. It was originally designed, created and manufactured by the American International Business Machines (IBM) Corporation. IBM sold its PC business to the Chinese company Lenovo in 2005; since 2007, all ThinkPad models have been manufactured by Lenovo.
The ThinkPad line was first developed at the IBM Yamato Facility in Japan; they have a distinct black, boxy design, which originated in 1990 and is still used in some models. Most models also feature a red-colored trackpoint on the keyboard, which has become an iconic and distinctive design characteristic associated with the ThinkPad line. It has seen significant success in the business market while certain models target students and the education market. ThinkPad laptops have been used in outer space and for many years were the only laptops certified for use on the International Space Station (ISS). ThinkPads have also for several years been one of the preferred laptops used by the United Nations.
History
Following the failure of the first laptop computer, the PC Convertible, IBM was the last of the major personal computer manufacturers to enter the fast-growing notebook market, launching the PS/2 Note in 1992. Building on the PS/2 Note, the ThinkPad was developed to compete with Compaq in the United States, whose LTE was the first commercially successful notebook PC; as well as Apple Computer's highly successful PowerBook, and Toshiba in Japan, whose Dynabook series of notebooks were similarly successful.

The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
