Texas Instruments (NYSE: TXN) is an American company known best for its semiconductors and graphing calculators. TI is the leader in DSP (digital signal processing) and DLP technologies (digital light processing). DSPs play an integral role in many modern cell phones, wireless routers and computers. These powerful processors receive, refine and display digital signals (e.g. voice and data that has been converted to digital). DLPs, on the other hand, are capable of projecting very high quality images. Furthermore, Texas Instruments is the strongest player in the analog market with a market share of 13%. In spite of this strong presence, however, it is still subject to substantial volatility stemming from changing demands for new technologies, uncertainties in pricing, and low margins of commodity chips. The company earned $10.4 billion in revenue and $1.5 billion in net income in 2009.^[1]
