It's difficult to pinpoint one exact activity that 50% of internet users do. Internet usage is incredibly diverse. However, here are some possibilities that are close to 50% user penetration:

• Social Media Use: Many studies suggest social media usage hovers around 50% to 60% of the global population. So it's likely close to half of internet users participate in social media in some way.
• Mobile Internet: Statistics show mobile web traffic makes up nearly 50% of all web traffic globally. This suggests close to half of internet users access the internet primarily through smartphones or tablets.

It's important to note that these are just a couple of examples, and the specific statistic you're looking for might depend on the source and region being studied.
