The History of Advertising
I saw this over on The Curious Brain and I think it’s absolutely superb. Put together by HubSpot (by some poor marketing exec who deserves a bloody big medal the size of their head, by the way), this hugely large but hugely impressive slide deck gives you a complete history of advertising. And it’s great.
(P.S. You probably will get RSI from clicking your mouse/trackpad/iPad screen 450+ times but it’s worth it.)
