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. This growth is being spawned 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
