Just as on the high street, online retailers need to advertise to grab attention, and this process can help match consumers to products. However, businesses should not mislead consumers for example by applying false or misleading descriptions, or by advertising prices that do not correspond to the actual prices charged.
Poor information provision by retailers can undermine competition and affect consumer behaviour. It makes it hard for consumers to compare final prices when searching online, and complicates their decision-making by requiring them to click through to additional pages or even register with a site to find the final price. In other words, it increases their ‘search costs’. It can also lead them to buy products with conditions and restrictions on them that they were unaware of. In the worst instances, consumers may actually find that they have paid more than they thought they had.

Optical materials were essential for many of the twentieth century’s most significant technological accomplishments. Humans have been intrigued with the development of optical materials and light behavior for centuries. Thomas Alva Edison, Max Planck, Albert Einstein, Max Born, and Niels Bohr presented significant optical theories and innovations that provided a foundation for research, development, and application of twentieth century optical materials. Significant optical milestones included the introduction of lens coating in the 1930s and lasers in 1960; fiber optics emerged by mid-century, and thousands of scientists innovated and adapted uses for optical materials in the following decades. Engineers established the International Society for Optical Engineering (SPIE) in 1955 to coordinate Professional efforts. Devamını Oku »
Before the Internet was created, the U.S. military had developed and deployed communications networks, including a network known as ARPANET. Uses of the networks were restricted to military personnel and the researchers who developed the technology. Many people regard the ARPANET as the precursor of the Internet. From the 1970s until the late 1980s the Internet was a U.S. government-funded communication and research tool restricted almost exclusively to academic and military uses. It was administered by the National Science Foundation (NSF). At universities, only a handful of researchers working on Internet research had access. In the 1980s the NSF developed an “acceptable use policy” that relaxed restrictions and allowed faculty at universities to use the Internet for research and scholarly activities. However, the NSF policy prohibited all commercial uses of the Internet. Under this policy advertising did not appear on the Internet, and people could not charge for access to Internet content or sell products or services on the Internet.

Internet Safety
Internet safety entails the guidelines and procedures implemented in public and private settings to protect the well-being of Internet users. Specific Internet safety measures include laws prohibiting illicit activity online and protecting children’s privacy; acceptable use policies that stipulate rules for children to access the Internet in schools; family guidelines and parental supervision; instruction in Internet literacy; and implementation of browser access controls and software to filter, block, and monitor children’s access to certain sites. As an educational tool, the Internet offers access to extensive resources and information; however, the speed and openness of this media necessitates awareness and intervention to promote safety and well-being.
