Resilience* as a Google search term in the United States, from Google Trends, 2004 – March 2013.
* Actual search term used: resilience -wow -warcraft. Why? Turns out resilience is a character attribute in World of Warcraft. The formula for the damage reduction provided by resilience was changed a few years ago, generating enough attention to noticeably inflate resilience search trends for a year or so. For the record: “Characters have no innate resilience. It can only be gained through external sources, e.g. equipment, elixirs, enchantments, and gems.”
