This document discusses research from a study on modern viewing habits called "The Multi-Screen Marketer". The study found that multi-tasking across devices while watching TV has become common, with over 60% of smartphone users and 65% of tablet owners reporting doing so. Younger age groups are more likely to multi-task. Tablet owners are more likely to take actions like purchasing in response to ads. However, consumers find mobile apps and sites from media companies unsatisfying. The rise of smartphones and tablets indicates multi-screen behavior will continue to increase as these devices become more prevalent.
