Technological convergence is the reason why cell phones have advanced beyond what was expected

People are using cell phones in a way, today, that was never imagined when they were first invented. The primary purpose of the cell phone was to make and receive phone calls anywhere and at any time. Instead of only being reached at home, and years later, in your car, with the cell phone, people could be reached on-the-go.

The cell phone was invented by Martin Cooper in the 1970s. It was called "the brick" because of its size-- 10 inches long and 2.5 pounds. Cooper's goal was that he "wanted people to have freedom to talk on the phone away from their cars."

Over the years, cell phones got smaller and smaller, and lighter and lighter. And as these devices became more portable, they also became more complex. The cell phone has changed as technological convergence has occurred. Advancements have led to cell phones being more than just phones. 

Today, your average Joe can be listening to music on their phone while sending out a text message. People can video chat, or FaceTime, check emails, and play games. They can even navigate places using a GPS application from your phone. You rarely see people without their cell phones and rarely see them making phone calls anymore with the many different means of communication out there.

Something that has grown drastically over the last few years in the United States and across the globe is social networking. People can now interact with others in a way that was never to be thought of when the first cell phones were invented. Examples of social networking sites include, Facebook, Twitter, Instagram, and Snapchat. People can now know what someone is up to at the click of a button on their mobile device. 

A lot of these services could not be done, though, without the convergence of cell phones and the Internet. The Internet is what allows us to access our emails, go on social networking sites, and use a GPS system to get places. Technological convergence is the main reason why our cell phones have advanced so far beyond what they were supposed to be when they were first invented.

*Note: The graph posted is from an article talking about how the size of cell phones have changed from 2000-2010. I do not think that this is a good graph because the title doesn't tell you what the graph is about. It just says "Thickness." Thickness of what? A better title would be, "The change in thickness of cell phones from 2000-2010." Also, another weak point of this specific graph is that there aren't any labels, especially on the y-axis. We don't know what those numbers mean or what they were measured in. Overall, since I told you that this is from an article about the evolution of the size of cell phones, from the graph, you can tell that the thickness of cell phones have decreased since 2000, meaning cell phones are getting thinner.
