IT security firm Optenet has published a report that categorizes the content on the Internet. Let’s assume their data are correct. Here’s what they say about what comprises the Internet (based on the company’s own classification scheme):

Online shopping represents the second biggest category (10.5 percent), followed by travel (7 percent), advertising sites (6 percent) and sports (4.5 percent).
Here’s the breakdown in graphical form:
