The Wall Street Journal (WSJ) has reported that both Facebook and Google has agreed to co-operate and assist one another in the case filed against them for online advertising dominance. It is described by Facebook as a big deal strategically. Both the companies facing the law suit treat it as the fight for their existence. If the authorities win the case, Google and Facebook could lose their grip on digital advertising and consumer data. There is a risk that either or both of these companies could be broken up. The outcome would take years to sort out.
