The Medium is the Message
Take a look at this ad. Would it work the same way if it were just in a magazine? Or on Instagram? No – it needs the real world interaction with the tunnel and the cars to make sense.
In this case the medium is incredibly important to the message, it not only enhances it but it makes the people who interact with it feel engaged. Perhaps they even feel like they’ve been eaten. I feel this is effective because it usually garners a reaction. A gasp, a laugh, a head shake – all these things are wanted in an advertisement because it usually means the person will remember. It also means when they see something related to your ad, in this case the rest stop, they will think of the ad and feel the same reaction. They may not stop, but I do think it will make someone stop and go in.
There are a lot of ads like this. It’s a cool idea and usually catches a positive reaction, but sometimes people become exhausted with always seeing advertisements. There is always someone trying to sell you something. This is an important thing to consider – how many ads are there like this in the area, how many ads are there in general, is this a place that would be more comfortable without an ad? The reason you should consider this is because it could grab a negative reaction from some, if not all the people who are engaging with your ad. If they have been bombarded with ads all day, it doesn't matter how witty yours is.
