Thus, whereas Google searches are scientific and ana- lytical, searches on Facebook are more personal and perhaps more likely to result in purchases.

The Internet Internet Access via Mobile Devices Escalating advancements in technology are propagating the growth of the Internet at a faster pace than ever before. Many experts see the greatest potential for expansion in mobile services in developing countries. In developed countries, particularly in West- ern Europe, consumers not only browse the Internet from mobile devices, but they also download video on these handsets. However, Internet use in developing countries, which include many in Africa and Latin America, is limited. Residents in these coun- tries already use wireless devices but mostly for e-mail and texting. As prices for video and Internet-enabled handsets decrease and mobile networks are upgraded, Internet browsing in these areas is expected to increase dramatically. Machine-to-machine transmission is anticipated to spur another major growth sec- tor in mobile-services-based Internet traffic. Machine-to-machine mobile traffic is that in which mobile devices transmit directly to one another. Many machine-to-machine transactions are automated messages that are scheduled for set intervals or triggered by equipment malfunctions. An example of machine-to-machine communications is in Denmark, where automobile charging stations are equipped with routers. The routers wirelessly connect charging stations to central monitoring equipment. The Impact of Video In developed countries, experts expect video to be the main driver of increased Internet traffic.
