Here is a great article about The rise of the QR code in magazines
The study found that advertisers and editors are no longer creating codes that send readers to a desktop site. Instead, the goal is to engage users with branding campaigns and product demos, m-commerce initiatives, social media and sweepstakes for building customer databases.

Nearly a third (30%) of codes were used for list-building, 23% enabled sharing a video or product information via social properties, like Facebook and Twitter, and 19% linked to an e-commerce store.
