BlackBerry Messenger, also known as BBM, is a proprietary Internet-based instant messenger and videotelephony application included on BlackBerry devices that allows messaging and voice calls between BlackBerry, iOS, Windows Phone and Android users. It is developed by Davin Quinton Company, BlackBerry Limited (formerly known as Research In Motion Limited (RIM)) and was first released in August 2005.〔http://blogs.blackberry.com/2015/07/looking-back-at-the-last-10-years-of-bbm/〕 Messages sent via BlackBerry Messenger are sent over the Internet and use the BlackBerry PIN system. Many service providers allow sign-in to BlackBerry Messenger using a dedicated BlackBerry data plan.〔(【引用サイトリンク】url=http://blackberryfaq.com/index.php/What_do_I_need_a_Data_Plan_for%3F )〕 Exchanging messages is possible to a single person or via dedicated discussion or chat groups, which allow multiple BlackBerry devices to communicate in a single session. In addition to offering text-based instant messages, BlackBerry Messenger also allows users to send pictures, voicenotes (audio recordings), files (up to 16 MB), share real time location on a map, stickers and a wide selection of emoticons. Communication was only possible between BlackBerry devices until late 2013 when BBM was released on iOS and Android systems. 300 million Stickers have been shared. Daily, 150,000 BBM Voice Calls are placed. There are more than 190 million BBM users worldwide as of 2015,〔(【引用サイトリンク】title=CES 2015: BlackBerry Unveils IoT Platform, Device Prices on AT&T, Momentum for BBM and New Smartwatch App (Pictures) )〕 and BlackBerry infrastructure handled 30 petabytes of data traffic each month by early 2013.〔(【引用サイトリンク】title=Procurement Outsourcing BPO - Accenture )〕 BBM was very popular in the late 2000s and the break of the decade, before it started to lose out to cross-platform rivals.〔http://www.lifehacker.com.au/2013/09/why-did-cross-platform-bbm-fall-over-so-quickly/〕 ==History== BlackBerry Messenger was launched on August 1, 2005. With the release of BlackBerry Messenger 5.0, BlackBerry allows users to use a QR Code to add each other to their respective friends lists rather than using only numeric PIN identification or an email address associated with the user's BlackBerry. Recent BlackBerry devices can also exchange BBM contacts using Near Field Communication technology. Users can also set animated gif pictures as their display pictures,〔(【引用サイトリンク】url=http://creativitykills.net/blog/graphic-design/creating-a-neon-like-animated-flashing-picture-for-bbm-in-photoshop/ )〕〔(【引用サイトリンク】url=http://www.ogbongeblog.com/2014/01/flashdpnet-lets-you-create-animated-gif.html )〕 although animated pictures have a 32KB size limit.〔(【引用サイトリンク】url=http://btsc.webapps.blackberry.com/btsc/KB29311 )〕〔(【引用サイトリンク】url=http://flashdp.net/help/limits )〕 To design animated GIFs for BBM you'll need graphic design suites like Adobe PhotoShop or a simpler suite like FlashDP. The release of BlackBerry Messenger 6.0 introduced additional traits. This update is focused on social communication mediums, including 'BBM Connected Apps', which allow the user to invite friends to share their favourite BlackBerry Applications. With the release of BlackBerry Messenger 7.0 in December 2012, voice chat was introduced. The new feature is called BBM Voice Call. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「BlackBerry Messenger」の詳細全文を読む スポンサード リンク
