A lot has changed in the world of audio over the last 170 years. Gone are the days of cranking a handle to make noise, replaced instead by silicon and circuity to pump out digital tunes. This beautiful illustration walks you through how and when those changes happened.
It's all here: starting with the key wind way back in 1840, then trotting through radios, Wurlitzer jukeboxes, tapes and Mini Discs, all the way up to the iPhone 5s. It makes you realise that music has always been a vital part of our lives -- it's now just delivered differently. You can buy a copy of the illustration from the guys at Pop Chart Lab for $US32.
