Pictured above is one of the interactive posters (New York, Lower East Side) that offers users a free CeeLo Green song. Another which was spotted by 9to5 Google is a giant screen at Port Authority in Manhattan. Upon touching the display, it will transition to show off three different Galaxy S3 selections with each option offering users downloadable content. Samsung has also announced plans to launch 3D advertisements that will play before a movie begins. The ad itself will also be interactive and will require the audience to wave their hands in the air to control a giant Galaxy S3 on the cinema’s screen. Sounds like a pretty expensive ad campaign to me, but then again we guess Samsung can afford it. If you’ve spotted any of Samsung’s interactive posters, let us know where in the comments below!
