There's a well-known delivery company that's found a way to park one of their trucks by the studio window of one of the national networks. For several days, during the broadcast, the logo of the truck was clearly visible in the background.

The news commentators caught on and mentioned it on the air, giving the company even more free publicity.

If they're going to broadcast live in public places, then they can only expect that some people are going to take the opportunity to get some exposure.
