Sonos sold $535 million worth of internet-connected speakers in 2013

Connected speaker maker Sonos announced Monday that it generated $535 million in revenue in 2013. This represents a 97 percent year-over-year growth, according to a company spokesperson. Sonos got a nice boost in sales after introducing its $200 Play-1 speaker last year, with some retailers struggling to keep the device in stock during the holiday season. This year around, Sonos is facing a number of new competitors, with everyone from chipset makers to startups like Beep rushing into the internet-connected speakers market.
