...but keep one foot on the ground.

If you have any lingering doubt that online advertising in the form of video is seeing explosive growth, consider this: Spending on online video advertising will reach $410 million this year, 82% more than was spent in 2005.

- The great desire among companies and their agencies for targeted ad messages in a familiar creative format

Another factor delivering high-percentage growth numbers is obviously the small base from which online video advertising has started.
