Texas Instruments has been working in manufacturing of discrete electronics since a very long time. It manufactures almost all electronic components from comparators to microcontrollers.

Initially an MSP-430 based development board was launched which was priced at $2.99!!
Recently TI has expanded the "Launchpad" line to include boards with C2000 and ARM Cortex Series processors. There are also some new development boards with special interface like USB and Wifi.
There are also a number of plug-in modules available to extend the functionality of your LaunchPad. TI calls these plug-in modules "Booster Packs". There are Booster Packs available for Alphanumeric LCDs, capacitive touch, motors drives and a number of different sensors.

Here is an overview of the LaunchPad product line.
