The digital media landscape is rapidly evolving in 2009. Key trends include a focus on measurability and differentiation as advertisers demand more accountability from budgets during economic uncertainty. Social influence marketing will become more mainstream as marketers learn to deploy social strategies more effectively. Mobile will continue growing but may be impacted by the recession, while opportunities in areas like mobile applications and location-based services will still emerge. Research and measurement methods must also evolve to account for the complexity of today's digital media environment.
