From the Jan. 5 NYT:

In cubicles across the country, lunchtime has become the new prime time, as workers click aside their spreadsheets to watch videos on YouTube, news highlights on CNN.com or other Web offerings.

The trend — part of a broader phenomenon known as video snacking — is turning into a growth business for news and media companies, which are feeding the lunch crowd more fresh content.

In some offices, workers coordinate their midday Web-watching schedules, the better to shout out punch lines to one another across rows of desks. Some people gravitate to sites where they can reliably find Webcasts of a certain length — say, a three-minute political wrap-up — to minimize both their mouse clicks and the sandwich crumbs that wind up in the keyboard.

“Go take a walk around your office” at lunchtime, said Alan Wurtzel, head of research for NBC. “Out of 20 people, I’m going to guarantee that 5 are going to be on some sort of site that is not work-related.”

The midday spike in Web traffic is not a new phenomenon, but media companies have started responding in a meaningful way over the last year. They are creating new shows, timing the posts to coincide with hunger pangs. And they are rejiggering the way they sell advertising online, recognizing that noontime programs can command a premium.
