NEW YORK (AP) — Yahoo's news site is launching a daily 90-second series based on its most popular stories.

Yahoo says it is teaming with Toyota and the production company Reveille to make "Who Knew?". The feature made its debut Monday on the popular news page.

Producers take the story that gets the most clicks on Yahoo's Web site and within 24 hours make a feature that offers background material. Something new will be posted each workday.

Woody Thompson, who created the "Pop Up Video" series for VH1, helped make this new series.

The first episode Monday offered details about the Shroud of Turin, including how many times it has been put on display.
