BlackBerry


BlackBerry

is a line of wireless mobile device that was introduced in 1999 as a two-way pager. In 2002, the more commonly known smartphone BlackBerry was released, which supports push e-mail, mobile telephone, text messaging, internet faxing, web browsing and other wireless information services. It is an example of a convergent device. Developed by the Canadian company Research In Motion (RIM), it delivers information over the wireless data networks of mobile phone service companies. BlackBerry first made headway in the marketplace by concentrating on e-mail. RIM currently offers BlackBerry e-mail service to non-BlackBerry devices, such as the Palm Treo, through the BlackBerry Connect software. The original BlackBerry device had a monochrome display, but all current models have color displays, and are market leaders in innovation, specifically surrounding multi-tasking operating systems and integration with backend messaging and collaboration and customised application systems.

RIM settled on the name with Lexicon Branding Inc., a branding firm out of California. Lexicon was also responsible for naming Apple's Powerbook. One of the executives thought the buttons on the device looked like tiny seeds in a strawberry. A linguist at the firm thought "strawberry" sounded too slow. "Blackberry" was suggested instead and chosen.

While including personal digital assistant (PDA) applications (address book, calendar, to-do lists, etc.) as well as telephone capabilities on newer models, the BlackBerry is primarily known for its ability to send and receive e-mail wherever it can access a wireless network of certain cellular phone carriers. Most current BlackBerry models have a built-in QWERTY keyboard, optimized for "thumbing", the use of only the thumbs to type, and there are also several models that include a standard cell phone keypad for typing, and two models that are full touch-screen devices with no physical keyboard. System navigation is primarily accomplished by a scroll ball, or "trackball" in the middle of the device, older devices used a track wheel on the side and newer devices like the Blackberry Bold 9700 or Curve 8520/8530 use a small pad for navigation "trackpad" instead of a trackballlink title. Some models (currently, those manufactured for use with iDEN networks such as Nextel and Mike) also incorporate a Push-to-Talk (PTT) feature, similar to a two-way radio.

Modern GSM-based BlackBerry handhelds incorporate an ARM 7 or 9 processor, while older BlackBerry 950 and 957 handhelds used Intel 80386 processors. The latest GSM BlackBerry models (8100, 8300 and 8700 series) have an Intel PXA901 312 MHz processor, 64 MB flash memory and 16 MB SDRAM. CDMA BlackBerry smartphones are based on Qualcomm MSM6x00 chipsets which also include the ARM 9-based processor and GSM 900/1800 roaming (as the case with the 8830 and 9500) and include up to 256MB flash memory.

The devices are very popular with some businesses, where they are primarily used to provide e-mail access to roaming employees. To fully integrate the BlackBerry into a company's systems, the installation of BlackBerry Enterprise Server (BES) is required, along with either Microsoft Exchange, Lotus Notes or Novell Groupwise email server applications.

BlackBerry is the world's second most popular smartphone platform, capturing 21% of worldwide smartphone sales in Q2, 2009. On 30 May 2009, RIM announced the number of BlackBerry subscribers has reached approximately 28.5 million.
