Ogilvy mobile social event: Photos

WPP Group PLC agency Ogilvy & Mather hosted a face-off between the top five mobile social networks on Friday.

Top executives from Foursquare, Buzzd, Loopt, Bright Kite and DoubleDutch battled it out to see which platform will eventually win out in the marketplace. The consensus: mobile social networking is here to stay and brands need to get with it.

Here are some photographs from the event hosted by Ogilvy's Digital Lab chief Maria Mandel at the agency's new headquarters on 636 Eleventh Avenue in New York. Also included are snapshots of the Ogilvy Digital Lab and the rooftop with Ms. Mandel giving a tour to this writer.

Senior Editor Giselle Tsirulnik cropped the images.
