Of her reasons for joining DoubleClick—the leading Internet provider of advertising—she says, the Internet “was like the Wild West. Because this is a young industry, [working for DoubleClick] provided the opportunity to apply the best practices used in Fortune 500 companies to practices that had yet to be written.”

DoubleClick’s first attorney, Ms. Wang now oversees a staff of 16 and manages worldwide legal affairs for the company, which has divisions in 24 countries. “No one here is ever bored,” she says with a laugh.

Key challenges include trademark and domain-name issues. “It’s extremely annoying to clear a mark and not be able to get the domain name,” she says. “Trademark law is four-dimensional, while domain names are one-dimensional. Apple is a strong mark, but you have the Beatles label [Apple Records] and the fruit with the same name, yet one Apple.com,” she explains. “Trademark law is more complex than the architecture of the Internet permits.”
