150 Brands - Celebrating 150 years of advertising on London Underground
In order to celebrate 150 years of advertising on the Tube, Exterion Media challenged commuters to identify 150 brands who have advertised on the London Underground, from product and strap-line based clues. One lucky person who correctly identified all 150 brands would win free travel for a year.
One 48-Sheet featured 75 snapshots of products and the other showed 75 famous strap-lines. The ads prompted people to visit 150brands.co.uk and ask for help using #150brands.
In just two weeks, the site received over 38,000 visits with users making over 1.5 million guesses. The game reached 99 countries and each player spent an average of 47 minutes on the site.
