What has changed in online marketing since 2007?

What will be an ideal response?

Since 2007, Facebook and other social networking sites have grown rapidly, smartphones have taken the market by storm, and local marketing has taken off. Prior to 2007, online marketing consisted of creating a corporate Web site, buying display ads on Yahoo and purchasing AdWords on Google, and sending e-mail. The display ad was the most prevalent form of online advertising. "Eyeballs" were the primary measure of a site's success, and "impressions" were the measure of an advertising campaign's success. Today, marketing is based on businesses marketing themselves as partners in multiple online conversations with customers and critics. Marketing requires firms to locate and participate in conversations happening on social media. Businesses can no longer tightly control their brand messaging. In addition, in 2007, mobile marketing was in its infancy, but it is now more than double the size of social marketing and location-based marketing.
