BREW (Binary Runtime Environment for Wireless) is an application development platform created by QUALCOMM for mobile phones. It was originally developed for CDMA handsets, but has since been ported to other air interfaces including GSM/GPRS. BREW is a software platform that can download and run small programs for playing games, sending messages, sharing photos, etc. The main advantage of BREW platforms is that the application developers can easily port their applications between all Qualcomm devices. BREW acts between the application and the wireless device on-chip operating system in order to allow programmers to develop applications without needing to code for system interface or understand wireless applications. It debuted in September 2001.
