Billboards are large outdoor advertising structures typically found in high-traffic areas, such as along highways or busy streets. They display colorful images and catchy slogans to grab the attention of drivers and pedestrians. Companies use billboards to promote their products or services, making them an effective way to reach a wide audience quickly. These advertisements can be illuminated at night or use digital screens to show changing messages. Billboards often feature well-known brands like Coca-Cola or Nike, and they play a significant role in marketing strategies. Their size and visibility make them a powerful tool for businesses looking to increase awareness and sales.
