把这一句，留给此刻的你
It's kind of debatable whether or not the advertisement model is effective. Like whether Nielsen works. For years, Nielsen has been based on sampling. It's not like an electronic bullet that hits your house that tells the people at networks at all times what you're watching.
广告模式是否有效还有待商榷。比如尼尔森是否有效。多年来，尼尔森一直基于抽样调查。它不像一颗电子子弹击中你的房子，随时告诉网络上的人们你在看什么。
