The active digital media universe shrank 0.1%, from 197.7 million users to 197.6 million users. The current digital media universe estimate stood at 236.2 million users, down 0.3% from 236.8 million users.

Top Parent Companies Lose Time
All of the top 10 parent companies/divisions in April 2010 lost month-over-month average time spent per person, while six lost month-over-month unique audience.
