I just gave 3 examples of products that succeeded brilliantly in a less mature market in western capitalist economies. WeChat might be an anachronism in 15 years just as AOL is today, although it continues to exist as a brand.

Incidentally I just glanced at the AOL website to remind myself how it's doing, and their ad banner offers a service to reduce the amount of paper junk mail you receive by signing up for AOL's managed unsubscription service. Less Information Age and more Irony Age.
