Ad block this!
This Danish bus-panel is a great example of what I mean.
Or is it?
Put this headline on a banner ad and it doesn't work.
Which means it must be the use of a bus-panel that's doing all the work.
Or is it, as is so often the case, a connection of two unrelated things.
Ad blocking is happening online.
So they chose to highlight the problem offline. On a bus.
