PwC collaborated with LinkedIn to develop a playful marketing campaign in the form of an online game that tested how well users knew their LinkedIn connections. The game emphasized that quality relationships were more important than quantity of connections. It generated over 844,000 impressions on LinkedIn and 453,000 impressions on Twitter, with over 14,500 people playing on average three times each. The successful campaign increased brand awareness for PwC's focus on building deep relationships with clients.
