Google Trends is a tool from Google Labs that shows the most popularly searched terms from the beginning of 2004 to now.
Their detailed charts show how often a particular search term is entered relative to the total search volume across various regions of the world, and in various languages.
Google Trends also allows the user to compare the volume of searches between two or more terms. Additionally there is also feature that shows news related to the search term overlaid on the chart showing how new events are affecting search popularity.
Since Google has launched this tool that lets anyone see what the world is searching for, and compare the world's interest in your favorite topics, there has been a huge increase for the demand of marketing companies that know how to research and analyze this type of data affectively. They have also since released Google Hot Trends which has proven to be equally as popular. This add-on was no more than a collection of the day to day trends that are surfacing on the net,which shows what people are searching for right now - the fastest rising search queries on Google. The best part about that was it was updated every hour. Which is huge if you are using an open source method of marketing to virally advertise online.
