Kleiner Perkins Caufield & Byers partner Mary Meeker recently published her annual global internet trends report. You can find a link to the presentation here but it is also embedded at the bottom of this post for ease of reference. Well worth a read as it contains lots of interesting data and insights.
For folks interested in regional trends, the deck includes a section on China (see slides 237-261). The China internet slides were contributed by Hillhouse Capital.
