The first iPhone launch in 2007 destroyed an entire industry

When Steve Jobs unveiled the iPhone in January 2007, Nokia held 40% of the global handset market and BlackBerry was the device of choice for business users. Jobs declared Apple was 'five years ahead of anything else'. Within four years, Nokia's market share had collapsed to under 15% and BlackBerry's was in terminal decline. The iPhone didn't just beat competitors — it made the entire existing competitive landscape irrelevant by redefining what a phone was.
