Facebook has rolled out a series of commercials about Facebook (News - Alert) to Facebook users on their Facebook feeds, according to re/code.

The amusing ads, which feature Facebook users coordinating events like sliding down snow-covered hills on couches fitted with skis, tango lessons, among others. These ads, created by the Wieden + Kennedy agency, also responsible for Nike’s ads, have been trickling out for the past month.

The ads may seem inconsequential, but there’s a real purpose behind them.

“Facebook helps you connect with your pals, so you can do cool things like take dancing lessons, run a marathon or plummet down a hill on a couch packed with attractive people while someone in a frog suit (?) cheers you on,” Peter Kafka wrote in re/code.

The ads run not into poignant territory, as well as humourous. One ad shows a young woman being comforted by a single friend after suffering a breakup and posting about it on the social networking site with the tagline “Sometimes, one friend is all you want.”

These ads will be mostly visible, apart from on Facebook’s official YouTube (News - Alert) channel, on Facebook’s news feed, which means that the ads are intended for people on Facebook. With the reach that Facebook has, this might seem strange for a site that’s become a cultural phenomenon, far beyond its origins as a site for college students a decade ago.

These original students and many other people have gone on to show off their lives as they graduate, get married, start families and connect with each other.

Facebook is trying to stay relevant and avoid the fate of some of the social networking sites that preceded it, such as Friendster and MySpace (News - Alert).

On the other hand, some people might find the logic of advertising to people who are already using the site questionable.

“This would be like a McDonald’s campaign that only ran in front of people who had already placed their drive-through orders,” Kafka wrote.
