Flashmobs became the method of communication. Radiotjänst needed a cost-effective idea & new method to reach its target. The decision to set a Swedish record in flashmobs was taken and a huge choir performed 5 unannounced flashmobs and sang the “Thank You Song” to 5 unknowing TV licence payers.

The aim was to create awareness for Radiotjänst and increase traffic to the 4 viral films produced and put on YouTube. To make this production happen, the idea was sold to 645 choir members to spread the message for free. Every movement, clap of hands and camera angle was planned in detail.

Saturday 14th November - the first of the 4 flash mobs appeared in central Stockholm. 645 people sang to 1 person in a public area and thanked them for paying their TV licence. No retakes and no professionals. This was all from one source, in one take - for real.

The viral films drove a lot of traffic. 1.1 million Swedes have seen the flashmob (12% of the Swedish population). The total net effect growth was 31,400 persons. The flashmobs appeared in almost all media we had communicated with. The biggest radio station played the sound from the flashmob. Newspapers published articles/interviews and/or videos on their websites. DN (Sweden’s largest daily newspaper) created a comic strip about the “Thank You Song”; our flashmob became a reference object and the appearance in blogs, Facebook and Twitter was complete. Our strategy to let the target group spread the message and create PR succeeded!
