Digital downloads had a short run as the top-selling format in the music industry. It took until 2011, a decade after the original iPod came out, for their sales surpass those of CDs and vinyl records, and they were overtaken by music streaming services just a few years later. Now, digital downloads are once again being outsold by CDs and vinyl, according to the Recording Industry Association of America. From a report: The RIAA released its 2017 year-end revenue report on Thursday, showing that revenue from digital downloads plummeted 25 percent to $1.3 billion over the previous year. Revenue from physical products, by contrast, fell just 4 percent to $1.5 billion. Overall, the music industry grew for a second year straight. And with $8.7 billion in total revenue, it's healthier than it has been since 2008, according to the report. Nearly all of the growth was the result of the continued surge in paid music subscription services like Spotify and Apple Music. Those services grew by more than 50 percent to $5.7 billion last year and accounted for nearly two-thirds of the industry's revenue. Physical media accounted for 17 percent, while digital downloads made up just 15 percent.
