Usability in focus: the Clear Channel Booking Tool is an easy to use and self-explanatory web platform. Small and medium enterprises can create an outdoor campaign online and book directly, without available know how or media manpower. From around 10,000 advertising spaces the availabilities are mapped in real time. All sites can be viewed by clicking on Google Street View. With the simulator "visualizer" the customer can insert his creative in a billboard and receive an online preview for the visual impact. The booking tool is supported by the video on the homepage which explains the direct way to the outdoor campaign in only 50 s.
