A teenager will respond with, "Because!".

It is what represents who a person is. Ringtones have become an extension of who we are, just as clothing has become. Not only can you now change the look and feel of your cell phone with creative and brightly colored skins and cases, you can also change the "voice" of your phone. Millions and millions of people are doing this!

With the expanding flexibility of cell phone settings, you can now have a different ringtone playing for every contact you have stored in your cell phone's phonebook. You can have a different image display for every contact that calls you. To a young person there is much fun to be had in tinkering with these hot items, and for the more "mature", there is great enjoyment from having your favorite tunes broadcast when someone calls.

This is making communications fun. People today want to customize everything and now with the broadening media market in the cellular industry, this is becoming easier than ever.
