HTC Corporation (Chinese: 宏達國際電子股份有限公司; pinyin: Hóngdá Guójì Diànzǐ Gǔfèn Yǒuxiàn Gōngsī, lit. Great Achievement International Electronics Corporation), formerly High Tech Computer Corporation, is a Taiwanese manufacturer of smartphones and tablets. Initially making smartphones based mostly on Microsoft‘s Windows Mobile operating system (OS) software, HTC expanded its focus in 2009 to devices based on the Android OS, and in 2010 to Windows Phone OS. Cher Wang (王雪紅), H. T. Cho (卓火土), and Peter Chou (周永明) founded HTC in 1997. Initially a manufacturer of notebook computers, HTC began designing some of the world’s first touch and wireless hand-held devices in 1998. The company is credited with creating the first Android smartphone, the first Microsoft-powered Windows CE smartphone with Siemens Mobile (2002) and the first Microsoft 3G phone (2005). Their first major product, one of the world’s first touch-screen smartphones, appeared in 2000. As an ODM for HP and Palm, HTC built the HP iPAQ and the Palm Treo 650.
