Here is a fun interactive social media campaign by the Belgium beer brand Maes.

The beer brand was not happy with its ranking as the second biggest Belgian Beer so they teamed up with advertising agency TBWA and created the ‘A barrel for every Maes’ campaign.

Maes is Belgium’s third most common surname so to boost their popularity, Maes the beer brand decided to give a free barrel of Maes to all the people with the same surname.

All they had to do was to sign up on Facebook, choose a a pub and share the date and their beer with all their friends.

The facebook page made it into the top 6% of most active pages world wide and 1 of every 20 Belgians visited the page.

Check out the video below that shows how some people even changed their name on facebook to receive the free beer!
