Addressable advertising has reached a critical point. At nearly 50 million, more than 42% of U.S. households are now addressable -- meaning advertisers can deliver the right ad to the right target on a national scale, and these numbers are growing. By 2020, Magna Global projects that nearly 60 percent of all U.S. homes, approximately 70 million, will be addressable. With this scale will come an influx of ad spending. A recent eMarketer report predicts addressable TV spend will swell by 144% in just the first two years, reaching an eye-catching $2.17 billion.
