Major online publishers and industry organizations said Monday that they've approved standards for counting online-advertising impressions, clearing a major hurdle to mainstream adoption of the medium after almost 10 years.
The move should go a long way to promote ongoing growth in ad sales by simplifying the buying and selling process, according the Interactive Advertising Bureau, a trade group that championed the standards.

For a number of reasons, a requested line of code may not be displayed on a computer screen. Advertisers, or their third-party ad networks, often count the impression only when the image itself is delivered.
