Technology is the application of science to address the problems of daily life. The fast pace of technological advancement means the advancements are continuous, but that not everyone has equal access. The gap created by this unequal access has been termed the digital divide. The knowledge gap refers to an effect of the digital divide: the lack of knowledge or information that keeps those who were not exposed to technology from gaining marketable skills
Media and technology have been interwoven from the earliest days of human communication. The printing press, the telegraph, and the Internet are all examples of their intersection. Mass media have allowed for more shared social experiences, but new media now create a seemingly endless amount of airtime for any and every voice that wants to be heard. Advertising has also changed with technology. New media allow consumers to bypass traditional advertising venues and cause companies to be more innovative and intrusive as they try to gain our attention.
Technology drives globalization, but what that means can be hard to decipher. While some economists see technological advances leading to a more level playing field where anyone anywhere can be a global contender, the reality is that opportunity still clusters in geographically advantaged areas. Still, technological diffusion has led to the spread of more and more technology across borders into peripheral and semi-peripheral nations. However, true technological global equality is a long way off.
There are myriad theories about how society, technology, and media will progress. Functionalism sees the contribution that technology and media provide to the stability of society, from facilitating leisure time to increasing productivity. Conflict theorists are more concerned with how technology reinforces inequalities among communities, both within and among countries. They also look at how media typically give voice to the most powerful, and how new media might offer tools to help those who are disenfranchised. Symbolic interactionists see the symbolic uses of technology as signs of everything from a sterile futuristic world to a successful professional life.
