The iPhone celebrates its fifth birthday today, and although it has only been in our lives a short while, its effect has been great. Here are five ways the device has affected us:

1. The computer becomes completely mobile.
2. Applications become a huge market.
3. The Internet is available 24/7.
4. Apple dominates the tech industry.
5. Gaming makes a widespread comeback.

The iPhone has revolutionized the way we think about computing, communicating, and gaming. Very few times has a single device so totally changed the way we look at the world. As marketers, it has provided unprecedented opportunities to reach audiences and communicate brand messages.
