Google Trends allows you to see what topics are trending online and over time. You can search specific terms to see their popularity and how it changes. For example, searching "LinkedIn" shows it dips at the end of each year when people are less active, while "MySpace" continues to lose popularity. Comparing "Facebook" in the US versus China shows it declining in the US but interest remaining in China. Changing the time frame for "Facebook" to 2004-present provides a clearer view of its product lifecycle. Google Trends also identifies related "Break out" searches seeing sudden increases, like "Facebook Espanol" rising due to new interest in its digital currency expansion in Spain.
