Old Spice: ‘The Man Your Man Could Smell Like’
Not every campaign on our list earns its place through decades of slow-burn consistency. Some earn it in about six weeks flat. Old Spice's 2010 relaunch, fronted by Isaiah Mustafa, is the campaign we reach for whenever the brief is “we need this to actually get shared,” because it remains one of the clearest examples of a brand understanding the internet before most of its competitors did.
Wieden+Kennedy built the original 30-second spot around a single confident, faintly absurd character talking directly to camera, then followed it with something braver: a run of personalised video responses, filmed and posted within hours, replying to real comments from fans, celebrities and competitors online.
The campaign in one line
Old Spice gave a stale, dad-shelf brand a self-aware, funny new voice - then proved it was really listening by answering the internet back, in character, in near real time.
Why it worked (and why it still matters)
The tone did the heavy lifting first. It didn't ask viewers to admire the product; it made them laugh, and it moved fast enough – line after line, scene after scene – that rewatching became part of the appeal. That's a very different job to the average body wash advert.
The follow-up videos are the part that really changed the conversation, though. Instead of treating the launch ad as the finish line, the brand treated it as the opening move in a conversation, replying to specific people by name with new, bespoke films made almost overnight. That kind of responsiveness simply wasn't normal in 2010, and it turned an audience that was watching into an audience that was participating.
It's also aged well as a case study precisely because it was built for a platform, not adapted for one. The pacing, the tone and the format all assumed people would be watching on a screen they controlled, sharing what surprised them, which is exactly what a huge number of them did.
What we take from it
A great script earns the first view. Being genuinely responsive – building in the capacity to react to your audience while the moment is still hot – is what earns the tenth. If your campaign only works as a broadcast and can't hold up a conversation, you're leaving most of its potential on the table.
