Karl Rosander, founder and president of podcasting platform Acast, details how Apple's devices have helped develop this nascent industry.
"Apple products and podcasting are intrinsically linked. The advent of the iPod in 2001 launched podcasts as we know them today, but the arrival of the iPhone liberated the format and completely removed the long-winded route of downloading and transferring from desktop to device," he told CNBC via email.
"Acast's business model only really works with a mobile platform. The iPhone laid down the original technology for this industry, and now 10 years later, it's amazing to see what it's become. Today's listeners are constantly plugged in to their smartphones accessing everything on-demand."
