In 2002, John MacFarlane and his co-founders began tinkering on what was then an ambitious idea: create a new way to enjoy music throughout the home, without wires. At the time, streaming and the iPod were brand new, and smart speakers were over a decade away. But the team at Sonos engineered a top-quality wireless sound system, and–with many fits and starts–integrated it with mobile technology and, eventually, Siri and Alexa. Along the way, John and his team contended with the early unreliability of WiFi, and faced stiff competition from much bigger companies. But today, Sonos is an established player in music, with projected sales of over $1.5 billion this year.  This episode was produced by Katherine Sypher with music composed by Ramtin Arablouei.
