Earned media (or free media) refers to publicity gained through promotional efforts other than advertising (paid media) or branding (owned media). There are many types of media available to online marketers and fit into the broad categories: owned, paid, and earned media. Owned media is defined as communication channels that are within one's control, such as websites, blogs, or email. Paid media refers mostly to traditional advertising. Earned media cannot be bought or owned; it can only be gained organically, when content receives recognition and a following through communication channels such as social media and word of mouth. Earned media often refers specifically to publicity gained through editorial influence of various kinds. The media may include any mass media outlets, such as newspaper, television, radio, and the Internet, and may include a variety of formats, such as news articles or shows, letters to the editor, editorials, and polls on television and the Internet. Many consider earned media to be the most cost-effective method of marketing. As a result, many companies are investing in earned media. The increased use of earned media is converging traditional owned and paid methods of marketing. The increasing use of earned media has provided marketers with new ways in which to interact and engage their customers. These innovative approaches are replacing traditional marketing methods such as email and banner ads, and provide innovative methods to find, optimize, and measure return on earned media investments.
