By definition, what may an advertisement include?

An advertisement is defined as any commercial message delivered to a customer, which encompasses a wide range of formats and media. This can include various methods such as print ads, television commercials, radio spots, online ads, and social media promotions. The key aspect of advertising is its intent to inform or persuade potential customers about products, services, or brand offerings, rather than being limited to specific types of media or content.

The other options are too restrictive. Focusing solely on messages related to discounts does not capture the full scope of advertising, as many ads promote brand awareness or new product launches without mentioning price reductions. Similarly, limiting messages to print media or social media platforms ignores the diverse array of advertising methods available today; effective advertising can occur across multiple channels, both traditional and digital. Thus, the broad definition of advertisements allows for flexibility and creativity in reaching target audiences.
