#7 RIM

The arrival of the first Apple iPhone in 2007 caused much fanfare and speculation that the BlackBerry might have its first serious competition. Boasting a powerful mobile browser, a new touch screen interface, strong multimedia capabilities and a bundled application storefront with many mobile apps, the iPhone was referred to as a "BlackBerry Killer" by some in the media. But RIM engineers insisted that iPhone cannot pull all these things together with any kind of useful battery life. Instead of taking the stock of the situation, they stuck with their obsessions that had kept the BlackBerry on top for years: minimizing power and data usage. With advances in battery tech and 3G networks coming online, these suddenly seemed less relevant, and RIM's hegemony collapsed before it could update its aging operating system.

#8 Myspace

Myspace is a social networking service with a strong music emphasis. Myspace was launched in August 2003 and was the most visited social networking site in the world. In June 2006 it surpassed Google as the most visited website in the United States. In April 2008, Myspace was overtaken by Facebook in the number of unique worldwide visitors, and was surpassed in the number of unique U.S. visitors in May 2009. Since then, the number of Myspace users has declined steadily in spite of several redesigns.
