Abstract
In recent years, many high-technology industries, ranging from “smart” cell phones to social networking Web sites such as Facebook Inc. and MySpace.com, have become platform battlegrounds. These markets require distinctive competitive strategies because the products are parts of systems that combine core components made by one company with complements usually made by a variety of companies. If a platform leader emerges and works with the companies supplying complementary products and services, they can together form an “ecosystem” of innovation that can greatly increase the value of their innovations as more users adopt the platform and its complements. However, companies often fail to turn their products into industry platforms.
