An iPod can hold roughly 10,000 songs. Increase the storage capacity every 13 years, something the size of an iPod could store one year of video in another few years. By 2015, you could store all the music ever produced. By 2019, you could 85 years of video – a lifetime’s worth of video. By 2020, the same sized device could store all the content ever created.
