Chapter 10: The Internet
Study
When Paul Baran began working for the U.S. military to design a communication system that could withstand the force of a nuclear strike, he had no idea that the project would be the beginning of arguably the greatest communication medium in history. The inclusion of academics in the ARPANet project led to a successful trial of a connected network between four universities. This new network served as the first segment of the modern Internet.
One factor that allowed the Internet to flourish and expand was the development of protocols, which led to across-the-board standardization of protocols. The original idea of packet switching outlined how digital messages would be sent from one network to another. Bob Kahn and Vint Cerf's development of TCP/IP allowed incompatible networks to work together seamlessly, thus providing the single network feel of the Internet. Other standards such as HTTP, URLs, and hypertext allowed further, consistent development of technologies.
Even in the infancy of the Internet, communication was a central concept. Ray Tomlinson's development of an e-mail program that incorporated solid standards became popular. Soon, that idea expanded to mass communication concepts such as mailing lists, discussion forums, and eventually blogs. Instant messaging is a real-time e-mail program that is an exception to the principle standard of the Internet: compatibility. Whether you wish to communicate with a friend in the next cubicle or across the country or the entire world population, there is an electronic “tool” to facilitate your conversation.
Tim Berners-Lee was instrumental in bringing the Internet to the public. His concepts of the World Wide Web and the software to make sense of the ocean of information began to make the Internet more user-friendly. Browsers gradually got better and companies sprang up with the sole purpose of bringing the Internet to consumers' households. Those early dial-up connections have seen a great deal of change in the last decade. Broadband network service opens up an entirely new world to Internet surfers by allowing them to download and view or listen to large media that would have previously been a nuisance. Wireless access allows people to break away from their traditional desktop workstations and sit on a park bench and enjoy the outdoors while working online.
The Web has allowed traditional media to expand their reach and depth of coverage, especially for breaking news. However, the net is the best suited for long-tail, upstart media. Exclusively online magazines, new filmmakers looking to get their films noticed, and bloggers with a quirky, personal point of view all have been able to carve out an online niche and attract an audience. The success of these long-tail ventures has certainly not gone unnoticed by the mainstream media companies. Traditional television networks making their broadcast programming available for download is a prime example of how the Net is changing the face of the traditional media the general public has become accustomed to.
