A genuine-sounding announcement by Zurich police was broadcast in the middle of the commercial break. They were looking for the driver of a car who was parked in a no-parking zone. An actor planted in the audience then had to get up and hurry out in front of 1,800 spectators. How embarrassing!After the film, free tickets for a test-ride by tram or bus were distributed to drivers, to prevent this happening to them too next time.

The live commercial was a big surprise, even though it only cost a fraction of a conventional cinema commercial: only 4000 Swiss francs (4300 US Dollars). It was repeated on twelve evenings and reached a total of about 20,000 people.In addition, newspapers, radio and TV reported on it and multiplied the advertising impact. This meant that over 1 million people heard the message: in Zurich it’s best to take the bus or tram.
