Which of the following is NOT an example of transit advertising?

Transit advertising refers to any advertising displayed on or within public transportation systems and vehicles. This includes advertisements placed in subways, taxis, and buses, as these are all forms of transportation that facilitate the movement of people and thus provide a platform for reaching commuters and travelers. These advertising mediums are specifically designed to target audiences who are on-the-go and could easily access promotional messages while using public transit services.

In contrast, print magazines are not categorized as transit advertising because they are published periodicals that do not belong to the framework of public transportation systems. They do not leverage the transit environment to deliver ads; instead, they are typically consumed in a stationary setting, away from the immediate influence of transit-related audiences. Therefore, recognizing that print magazines do not fit the definition of transit advertising makes it clear why this option is the correct answer.
