Ads in 2018 are anything but straightforward -- but that's kind of the point.

Consider for a minute that this green rainbow is an ad:

And this "Ketchup" jersey is also an ad:

Once easily defined in terms of medium, today's ads are designed to slip seamlessly into our lives without causing noticeable disruptions (whether or not they always succeed in this area is another story entirely).

With advertisers working harder than ever to create unexpected (and undetected) ad experiences, a clear definition of advertising is more difficult than you might think to pin down. If you're here, I'm guessing you're looking for a succinct, simple definition of advertising. Maybe even -- and I'm reaching here -- in 50 words or less? I won't delay you further.

To be considered an ad, messages don't need to specifically mention a product or service. In fact, many of the ads you encounter on a daily basis are more about cultivating a general sense of awareness for a brand than directly influencing buying decisions right away. 

As a general rule of thumb, if you think it's an ad, then it probably is.
