T-Mobile: “Dance” [02:50]# The makers of this commercial have borrowed heavily from the “flash mobbing” phenomenon, which brings together groups of people to stage seemingly spontaneous events in public places. In this particular case, staged on January 15, 2009 at Liverpool Street station on the stroke of 11am, people suddenly start to dance. As the music plays, ever bigger crowds are sucked into the choreography (a total of 350 dancers were used). Lookers-on are impressed and amazed by the event, some joining in, others pulling out their mobile phone to tell their friends about it. Sign-off: “Life’s for sharing. T-Mobile.”
