The 2012 Olympic Games are set to kick off next week in London, and several B2B companies are ready to make a big advertising splash. As BtoB Magazine reports, companies such as Citigroup, Dow Chemical Co., General Electric Co., Panasonic and Visa have all made major ad buys for the upcoming Games. Sure, some of these companies (Visa, Panasonic, Citigroup) target the consumer segment as well as businesses, so we can understand why they’d decide to run ads during one of the most-watched events of the summer. But what about Dow Chemical and General Electric? Is their move to run ads during a major TV event (much like GE in the Super Bowl) another sign that the lines are blurring between B2B and B2C advertising — a topic we discussed last week? Let us know what you think in the comments.
