After initially making smartphones based mostly on Windows Mobile, HTC expanded its focus in 2009 to devices based on the Android, and in 2010 to Windows Phone. A September 2013 media report stated that HTC's share of the global smartphone market is less than 3 percent and its stock price has fallen by 90 percent since 2011. The HTC Dream, marketed by T-Mobile in many countries as the T-Mobile G1 or Era G1, was the first phone on the market to use the Android mobile device platform.
