At its peak, BlackBerry sold more than 15 million smartphones every three months.
This year, the company's handsets represent less than one per cent of smartphones sold worldwide, according to Gartner, an unprecedented decade-long sales crash.
But the BlackBerry still has a name and a reputation, and TCL Communications revealed plans to revive both in a keyboard-toting smartphone unveiled at the world's biggest mobile phone show this morning.
The BlackBerry KEYone features a thumb-friendly, 35-button backlit keyboard like its phone of the past, and TCL has paired it with a 4.5-inch touchscreen, Google Android software, and a 12-megapixel camera.
TCL Communications chief executive Nicolas Zibell said the company was determined to breathe new life into the BlackBerry name and create a new generation of devoted fans.
