Analysis - Google+ Struggles to Attract Brands, Some Neglect to Update - NYTimes.com

Excerpt from a Google+ advertising reality check

"An informal survey by Reuters showed that of the 100 most valuable global brands in 2012 ranked by Millward Brown, a media research firm owned by ad giant WPP, 72 have a presence on Google+, compared with 87 on Facebook.
However, roughly 40 percent of the brands with pages on Google+ have either never posted any content, or do so infrequently. Seventeen brands, including Nike and Pepsi, had not posted to their Google+ page in more than a week.
The McDonald's Google+ page did not have a single posting. A spokeswoman for the fast-food chain said only that the company was "not active" on Google+."
