参考答案
正确答案：B
解析：本题问：商业杂志说“It will represent a‘watershed moment’in the evolution of the internet as anadvertising medium”意指什么。相关部分在文中第一段开头，提到广告时代预测本年度谷歌和雅虎两大网络公司的广告收入将可以和美国三大电视网在黄金时段的广告总收入相抗衡，称这是因特网作为广告媒介这一发展过程中的一个“watershed moment”。本题理解的关键是“wa—tershed moment”，根据上下文可以判断网络广告已经对电视广告构成威胁，并已取得显著成绩。因此，网络广告的出现为因特网成为广告媒介提供了契机。故B“谷歌和雅虎的成功成为网络广告发展的转折点”为正确项。
