The Open Handset Alliance (OHA) was a consortium led by Google that develops the Android mobile operating system. Its member firms included HTC, Sony, Dell, Intel, Motorola, Qualcomm, Texas Instruments, Samsung Electronics, LG Electronics (formerly), T-Mobile, Nvidia, and Wind River Systems.
The OHA was established on November 5, 2007, with 34 members, including mobile handset makers, application developers, some mobile network operators and chip makers. As part of its efforts to promote a unified Android platform, OHA members are contractually forbidden from producing devices that are based on competing forks of Android. While not officially stated, the alliance has remained dormant, with many OHA partners having moved out of the smartphone market.
