第二段说之后后来那个流行的原因。但是后来，托马斯的G在商业上超过的爱迪生的。主要原因是被卖给的了一家大公司。该公司对该产品进行了一定的经营活动。另外一个原因是由于爱迪生的产品的市场定位是在一般的商业用户，而另外那种则面向广大的普通用户。而且，后者认为他们除了提供留声机之外，更重要的是还要提供相关内容(唱片)。该公司后来请了当时著名的歌剧明星来灌制唱片，为的是提供democratic assess for the public a kind of cultured and privileged lifestyle。最后一句是说Victor这边有great singers的support, Edison爷爷那里是没有的.

留声机的那篇。狗狗不太全，我来补充一下。就是说Edison和另一个也是E开头的人称它为E2吧，都发明了留声机。刚开始的时候，Edison的留声机比较畅销，原因是edison的名气大，还有同时实现了recording和playback的功能。但是后来，E2 的销量后来居上，原因是他除了面向business还面向individual customers。具体做法就是通过reputation老获取顾客的欢迎。他们请了当红的明星来录专辑，卖的很好。题忘得差不多了，挺简单。唯一一个不确定，问edison的marketing方法有什么limitation。楼主选的是 fails to 考虑customer的需求。
