When Red Bull started selling in London, it needed a low budget way to increase brand awareness.
It chose a very simple route.
In London, Red Bull was against stiff competition in the early days. The soft drink/energy drink sector is just a massive uphill battle with around a 90% failure rate.
Going against the odds, Red Bull went to every single trash can in London and filled them with empty Red Bull cans.
That's how they created a perception that there was a massive demand for this unknown product. The rest is history.
Today, this Bull is dominating its niche, is the brand leader in the sector, and number one for top of head recognition.
Whoever thought up this idea deserves a medal!
