Advertising media selection is choosing which type of advertising to use. It means figuring out what type of advertising will reach the most people and be the most effective. Some types of advertising media, or ways to get a message out, include television, radio, newspapers, magazines, billboards, the internet, and social media. To select the right one, you need to think about the type of people the ad is trying to reach and the cost of using each type of media. For example, if you want to reach young people, you might use social media or the internet to advertise, but if you want to reach older people, you might use television or radio. It all depends on who you are trying to reach and how much money you have.
