Today, a plane flew over the New England Patriots practice field with a banner message reading 'Cheaters Look Up! @JetsFanMedia.'

It could hve been easy to post something like this on social media, but the idea of seeing somethign fly through the sky really drives the message home. 

Airplane banner ads may seem a bit antiquated but they're still a great way to advertise your product or service, or share a message to a large crowd of people.
