http://wwww.copower.org/manyfacesonevoice.htm I like at&t's slogan "Your world. Delivered." In this day and age much of our world is, in fact, on our phones, and therefore this advertisement is accurate. The advertisement also gives the consumers the feeling of safety in that the word "delivered" has the connotation of not having to do any work and having the service just given to the consumer, which is what most people look for in a service provider. This slogan is also simple, making it easy to remember.
