Display advertising has long held the promise of a 1-to-1 communication between marketers and consumers. Today, advertisers - both large and small - are getting better results through innovations that make it easier for them to find the consumer they're looking for, and deliver a relevant message.
Display advertising is going through the biggest and most important revolution in its history. In fact, it's been predicted that by 2020, this could be a $200B industry. This growth is driven by an advertiser's ability to do things better in 3 key areas:
* Reach the right consumers efficiently, through granular targeting, and real-time buying
* Build more relevant and engaging ads with dynamic, optimized rich media ads
* Reach consumers in new environments like mobile internet and online video
