Accessed August 8, 2007.Internet censorship See censorship <strong>and</strong> theInternet.Internet cafés <strong>and</strong> “hot spots”Internet cafés (also called cyber cafés) are public placeswhere computers are connected to the Internet <strong>and</strong> availablefor use for a fee by the hour or minute. Many Internetcafés also sell c<strong>of</strong>fee <strong>and</strong> food. Combining the social ambience<strong>of</strong> a traditional c<strong>of</strong>fee shop <strong>and</strong> the attraction <strong>of</strong> theInternet, many Internet cafés acquire a regular clientelefrom students to adults.These venues appeared first in the mid-1990s <strong>and</strong> spreadrapidly as their popularity grew. While the most commonactivities at most Internet cafés are to check e-mail, sendtext messages, or browse the Web, some locations specializein gaming (see online games), providing more powerfulmachines running games over a local network. Suchgaming centers have been particularly popular in Asia.Internet cafés have grown most rapidly in countries thatare becoming more urban <strong>and</strong> industrial but where manypeople cannot yet afford their own computers. The moststriking example is China, which had 113,000 Internet cafésin as <strong>of</strong> 2007. In keeping with its strict policies, however,the Chinese government closely monitors activity at Internetcafés (see censorship <strong>and</strong> the Internet).Hot SpotsThe number <strong>of</strong> dedicated Internet cafés in the UnitedStates <strong>and</strong> many other highly developed countries has beendeclining in recent years. This is largely due to the growingnumber <strong>of</strong> people who connect to the Internet through theirown laptops <strong>and</strong> other mobile devices (see pda <strong>and</strong> smartphone).Thus many locations, including c<strong>of</strong>fee chains suchas Starbucks, do not provide machines, but simply <strong>of</strong>ferwireless Internet access (see Wireless <strong>and</strong> mobile computing).Areas where one can make such a wireless connectionare called “hot spots.” Today virtually all majorhotels <strong>and</strong> airports provide hot spots; there is normally afee for access as with Internet cafés. (The fee is collected byrouting all access through a portal.) However, a number <strong>of</strong>venues <strong>of</strong>fer free Wifi access.Users <strong>of</strong> Internet cafés or hot spots should be awarethat they are sharing an ad hoc network with strangers <strong>and</strong>may be exposed to malicious s<strong>of</strong>tware. Passwords or othersensitive data may be “sniffed” using special s<strong>of</strong>tware. Itis therefore generally a good idea not to conduct financialtransactions or otherwise send sensitive information whenconnected to such venues, unless one has provided forencryption or can access a virtual private network. Additionally,users connecting their own machines to a hot spotshould have up-to-date firewall <strong>and</strong> antivirus s<strong>of</strong>tware.Further ReadingBradley, Tony, <strong>and</strong> Becky Waring. “Complete Guide to Wi-Fi Security.”Available online.

In many casessuch facilities have given way to simple “hot spots,” where userscan wirelessly connect their own laptops or PDAs. (Qin Ying/Panorama/The Image Works)Internet organization <strong>and</strong> governanceThe Internet is remarkable as a modern institution in that,while the technology was developed with considerable governmentfunding, the Net as we know it today is remarkablyfree <strong>of</strong> externally imposed authority or regulation. This isin sharp contrast with earlier communications technologiessuch as the telegraph <strong>and</strong> telephone, which were generallytightly regulated or even run by a government departmentsuch as the Post Office. In part this was due to the complexity<strong>of</strong> the technology <strong>and</strong> the fact that many political leadershad little familiarity with it <strong>and</strong> its implications. (Also, thespeed <strong>of</strong> growth has been overwhelming in recent years,considering that the World Wide Web in its modern formwas scarcely a decade <strong>and</strong> a half old as <strong>of</strong> 2008.)Institutions <strong>of</strong> Self-GovernanceWhile the Internet is not rigidly controlled, the need forinteroperability <strong>and</strong> orderly advances in technology hasled to the emergence <strong>of</strong> several organizations that provide
