Today they up-dated the chart to show growth through April.
Interestingly, you can see that growth eased somewhat in April. The number of online sessions, domains visited, web pages per person per month, all declined somewhat. The active digital universe was also down about a percentage point for April.
This may reflect global economic conditions. People may be spending less on Internet access time, or they might be deciding to use their time differently for various reasons. Up-dated survey research could help uncover changing perceptions of time use and motivations.
Here's the link to Nielsen Online. You can follow their monthly chart on global Internet use, as well as charts showing some country-specific information on the most popular parent domain names, such as Google, Yahoo!, and FaceBook.
