Tobacco advertising is when companies advertise their tobacco products, like cigarettes, cigars, chewing tobacco, etc. Companies use TV, radio, newspapers, magazines, billboard signs, and other types of advertising to promote their products. They might use special images or slogans to make their products seem cool or appealing, but the reality is that tobacco is very bad for your health. In many places, tobacco advertising is not allowed because it can encourage people to start using tobacco.
