Hi there! "Transit media" is when advertisers put their messages on things that move around, like buses, trains, or taxis. It's kind of like a moving billboard.
Think of it like this: when you're riding a bus or train, you might see ads on the sides or inside of the vehicle. Those ads are a type of transit media.
The reason advertisers use transit media is because it can reach a lot of people. Lots of people ride buses and trains every day, so putting an ad on one of these vehicles means it will be seen by a big audience.
But transit media isn't just limited to buses and trains. It can also include ads on things like bike share programs, airports, or even in taxis. So basically, anytime you see an ad on something that's moving around, you're looking at transit media.
