You can help ThinkWiki by expanding it. |

create some icons for certain technologies, for example: infrared, wwan, webcam, infrared webcam, power bridge, thinkshutter, backlit keyboard, adaptive keyboard row, etc. you'll get the idea |

This is an overview of the history of the ThinkPad brand.

**NOTE!**

Some of the release dates may be incorrect, especially for the newer models.

IBM has an old webpage that minimally details the history of the ThinkPad brand too.

## Lenovo ThinkPad

Lenovo completed the ThinkPad brand acquisition in May 2005. As part of the deal, select ThinkPads continued to be sold under the **IBM ThinkPad** brand for years afterwards. The said brand was however, discontinued mid-way in production of the T61/R61/X61 models. This is also the reason why models after the T61, no longer featured the old IBM branding.
