Outdoor advertising, for most people, a picture of big billboards on the highway comes to their mind. Actually its more than these big, colourful billboards. It can be, but is not limited to, phone booths, taxis, shopping centres, benches, trains, buses and transit lines. Outdoor referred to as Out-Of-Home advertising, which engages & communicates with people while they are out of their home and has a potential to reach active consumers. Unlike other mediums, outdoor advertising does not need to be invited in. Outdoor advertising is part of the environment, therefore cannot be turned off like television and radio. The viewer has no control on whether they see it or not giving your campaign more impact for a longer period of time than the viewer may expect.
