Also, DoubleClick does the same. Interested children's shoes can check, doubleclick, the world's largest advertising intermediary platform, has the most powerful advertising Special Database publishing algorithm, covering the world's high-quality customer base, because there is no user base of its own, how did the stock price plummet and finally be forced to sell for google. Example 2: 263 free e-mail office, once the first in the market, in pursuit Special Database of income; forced to upgrade to a fully paid version; their logic is that email addresses are similar to mobile phone numbers, and high-end people.
Will not change their email addresses at will; the result is ridiculous , not only did they lose free users, but also paid users, a wonderful case of the Chinese Internet. Example 3: QQ, Ma Huateng Special Database did not have the idea of creating an operating platform himself when he first started QQ, but just wanted to sell the system to operators. As a result, the operators were assessed from the idea of software engineering. How Special Database many people and months did this thing make? , QQ can’t even sell 1 million RMB! 1 million RMB, you read that right!! At that time, Ma Huateng sold QQ for almost 800,000 RMB.
But just saw the news of AOL’s acquisition of ICQ at this time, it seems that more than 100 million US dollars , is calculated according to how much a user costs, pony's Special Database eyes lit up, it turns out that on the Internet, users = money! Then he re-evaluated according to this valuation, as a result, various Internet elites in China laughed at it, and various white-collar users of Sina can still be counted. Some money, QQ children are also valuable? Stop Special Database kidding! IDG took it seriously, the South Africans took it seriously, and those elites said, look, SB Africans, have been fooled by Ma Huateng.
