News is the most popular online video category, according to a study recently conducted by the Online Publishers Association.

OPA surveyed more than 1,400 online video users, who cited news and information as their favorite category. The study also found that users respond to video advertising.

Of the 80 percent of viewers who watched a video ad online, the study said 52 percent took some sort of action, whether it’s checking out a Web site (31 percent), searching for more info (22 percent), going into a store (15 percent) or making a purchase (12 percent).
