Google Trends gives an insight into search patterns by letting you see how often something was searched for compared with other terms. You can compare up to five search terms. Graphs will be shown, but only if there is enough search volume on the terms you enter. You can narrow your results down by month and year (back to the start of 2004), or by region. Google Trends is a product of Google Labs and was launched at the second annual Google Press Day on May 10, 2006.
