Not long ago, the big retailers were considered as the sharks eating the small independent retailers. Today, these sharks are getting eaten by the web savvy companies. Booksellers are good examples. Borders is bankrupt. Barnes and Noble is not doing so well. These are the same companies that were thought to drive independent booksellers out of business. Now they are going out of business. The Internet companies may the new Goliaths. However, the new Davids may be the ones who combine web savvy with mobility and social networks. I see business very similar to biology. The species (companies) that survive are the ones who are the most adaptable to the change in the environment [Darwin].
