At its peak, BlackBerry dominated the smartphone market. Its devices were trusted by governments, executives, and organizations around the world for their security, reliability, and physical keyboard experience. When Apple introduced the iPhone in 2007 and the smartphone market began shifting toward touchscreens, software ecosystems, and consumer-focused experiences, BlackBerry continued investing heavily in the strengths that had originally made it successful. Over time, market share declined as competitors adapted more quickly to changing customer expectations and technological trends.
