For one week, 21 bus and tram stops in downtown Helsinki will bear a non-commercial message. 1458 people participated in renting them for one week – at 5896.62 euros, the average contribution was 4.20€ per person. The word was spread through a Facebook page from the beginning of December. Within 1.5 months, the page reached almost 6000 fans and it took only two weeks to collect the needed amount of money.
