Google Trends is a new feature offered by Google, which according to Google is, "an unbiased sample of Google search data. Only a percentage of searches are used to compile Trends data.
Google Trends also provides information on the top charts, the most search YouTube videos, and most interestingly, a feature called "Google Correlate." Google Correlate finds search patterns which correspond with real-world trends." This is a great tool to conduct analyses on specific inquiries you may have for a particular class or research project.
Currently, as seen in the image below, the 2016-17 NFL Season, the Presidential Inauguration, and the Golden Globe Awards are the most searched topics "trending" on Google.
