…To understand the economics of tech companies one must understand the difference between fixed and marginal costs, and for this Amazon Go provides a perfect example…
It was expensive to develop mainframes, but IBM could reuse the expertise to build them and most importantly the software needed to run them; every new mainframe was more profitable than the last.
It was expensive to develop Windows, but Microsoft could reuse the software on all computers; every new computer sold was pure profit.
It was expensive to build Google, but search can be extended to anyone with an Internet connection; every new user was an opportunity to show more ads.
It was expensive to develop iOS, but the software can be used on billions of iPhones, every one of which generates tremendous profit.
It was expensive to build Facebook, but the network can scale to two billion people and counting, all of which can be shown ads.
上个月在图书馆无意找到这本《公共关系实务》( The Practice of Public Relations 8th Edition ), 到今天已经翻了小半本。觉得实在应该为这本爱不释手的图书写点什么, 做些记号。这本《公共关系实务》(以下简称《实务》)是由具有30年经验的公关老手Fraser P.Seitel 先生所著。Seitel 曾担任大通曼哈顿投行资深副总裁和公共事务董事10年之久, 同时是博雅公关的高级咨询顾问。就这本书来说, 我们可以看到Seitel 具有非常系统的PR知识体系, 并且有非常清晰的教授思路, 难怪。毕竟PR也是一门沟通的学问嘛。
