What are digital marketing channels?

It was in October 1994 when the first web-based banner ad was born courtesy of an advertising campaign for AT&T. The copy read: “Have you ever clicked your mouse right HERE? YOU WILL”. In the four months that followed, 44% of internet users had actually clicked on it, giving the company heaps of advertising mileage.

The publishing of that ad, which is now better known as display ad, has been referenced as the earliest form of digital marketing. Then again, display ad is only part and parcel of the entire digital marketing industry.
