The document discusses the results of Nielsen's 2013 Global Survey of Trust in Advertising, which polled over 29,000 people across 58 countries about their trust in various forms of paid, earned, and owned advertising. It finds that recommendations from friends and family remain the most trusted form of advertising, followed by owned advertising on branded websites. While trust in traditional media like television, magazines, and newspapers remains strong, trust in online and mobile advertising is growing significantly. Regions with the highest levels of trust in advertising are also most likely to take action based on ads.
