Advertising campaign

An advertising campaign is a series of messages that a company puts out to try and get more people to buy their product or use their services. They do this by showcasing how great the product or service is, talking about how it can help people, and being creative to grab people's attention. Companies usually advertise on things like TV, radio, newspapers, and billboards. This way, people will see the campaign and be more likely to buy the product or use the service.
