News Summary: Coke, Samsung pull Vietnam site ads

ADVERTISERS OUT: Coca-Cola and Samsung have pulled advertising from a popular Vietnamese website notorious for providing unlicensed downloads of Western and local songs, Zing.vn.

THE WEBSITE: Zing's young, tech-savvy users have made it attractive to companies wanting to promote their products in a fast-growing Asian market. It's the sixth-most visited website in the country, which has 30 million people online. Other multinational companies that have advertised on Zing include Canon, Yamaha, Intel and Colgate Palmolive.

WHAT IT MEANS: The moves by Coke and Samsung are a rare victory against online piracy in a country where it has grown unchecked.
