 Table-Top Displays: Offer a less-expensive exhibiting option for smaller events and feature a lightweight display that sits on top of a table.

The Geolocation API defines a high-level interface to location information associated only with the device hosting the implementation, such as latitude and longitude. The API itself is agnostic of the underlying location information sources. Common sources of location information include Global Positioning System (GPS) and location inferred from network signals such as IP address, RFID, WiFi and Bluetooth MAC addresses, and GSM/CDMA cell IDs, as well as user input. No guarantee is given that the API returns the device’s actual location.

另一个例子是美国市场的Netflix和blockbuster。2004年左右的时候,blockbuster和Netflix在DVD 租赁市场上竞争的非常激烈。Netflix提供很多品类的DVD租赁,同时,Netflix网站也会根据用户的喜好,给用户推荐那些票房表现不好但非常适合该用户的影片。这一策略收到了很好的效果。为了和Netflix竞争,blockbuster依赖于自己品类多的优势,开始对自己的服务降价,并在DVD送达服务上力争匹配竞争对手Netflix。同一时期,Walmart也认为自己具有品类和快速送达的优势,也开始涉足DVD租赁服务。这些瞄准竞争对手当前最佳实践的战略,最后都失败了。因为在接下来的几年,netflix将自己的优势统统建立在流媒体播放( streaming)业务,以及能够深度了解用户的推荐引擎上面。 <
