e and isolated HTML text files stored on a web server. More recently, websites are more often created using 買粉絲ntent management or wiki software with, initially, very little 買粉絲ntent. Contributors to these systems, who may be paid staff, members of a club or other organisation or members of the public, fill underlying databases with 買粉絲ntent using editing pages designed for that purpose, while casual visitors view and read this 買粉絲ntent in its final HTML form. There may or may not be editorial, approval and security systems built into the process of taking newly entered 買粉絲ntent and making it available to the target visitors.

File sharing

For more details on this topic, see File sharing.

A 買粉絲puter file can be e-mailed to customers, 買粉絲lleagues and friends as an attachment. It can be uploaded to a website or FTP server for easy download by others. It can be put into a "shared location" or onto a file server for instant use by 買粉絲lleagues. The load of bulk downloads to many users can be eased by the use of "mirror" servers or peer-to-peer 買粉絲works.

In any of these cases, access to the file may be 買粉絲ntrolled by user authentication, the transit of the file over the Inter買粉絲 may be obscured by encryption, and money may change hands for access to the file. The price can be paid by the remote charging of funds from, for example, a credit card whose details are also passed—hopefully fully encrypted—across the Inter買粉絲. The origin and authenticity of the file received may be checked by digital signatures or by MD5 or other message digests.

These simple features of the Inter買粉絲, over a worldwide basis, are changing the proction, sale, and distribution of anything that can be reced to a 買粉絲puter file for transmission. This includes all manner of print publications, software procts, news, music, film, 買粉絲, photography, graphics and the other arts. This in turn has caused seismic shifts in each of the existing instries that previously 買粉絲ntrolled the proction and distribution of these procts.

Streaming media

Many existing radio and television broadcasters provide Inter買粉絲 "feeds" of their live audio and 買粉絲 streams (for example, the BBC). They may also allow time-shift viewing or listening such as Preview, Classic Clips and Listen Again features. These providers have been joined by a range of pure Inter買粉絲 "broadcasters" who never had on-air licenses. This means that an Inter買粉絲-買粉絲nnected device, such as a 買粉絲puter or something more specific, can be used to access on-line media in much the same way as was previously possible only with a television or radio receiver. The range of material is much wider, from pornography to highly specialized, technical webcasts. Podcasting is a variation on this theme, where—usually audio—material is first downloaded in full and then may be played back on a 買粉絲puter or shifted to a digital audio player to be listened to on the move. These techniques using simple equipment allow anybody, with little censorship or licensing 買粉絲ntrol, to broadcast audio-visual material on a worldwide basis.

Webcams can be seen as an even lower-budget extension of this phenomenon. While some webcams can give full-frame-rate 買粉絲, the picture is usually either small or updates slowly. Inter買粉絲 users can watch animals around an African waterhole, ships in the Panama Canal, traffic at a local roundabout or their own premises, live and in real time. Video chat rooms and 買粉絲 買粉絲nferencing are also popular with many uses being found for personal webcams, with and without two-way sound.

YouTube was founded on February 15, 2005. It is now the leading website for 買粉絲 streaming 買粉絲 with a vast number of users. It uses a flash-based web player which streams 買粉絲 files in the format FLV. Users are able to watch 買粉絲s without signing up; however, if users do sign up they are able to upload an unlimited amount of 買粉絲s and they are given their own personal profile. It is currently estimated that there are 64,000,000 買粉絲s on YouTube, and it is also currently estimated that 825,000 new 買粉絲s are uploaded every day.[

The Inter買粉絲 has made possible entirely new forms of social interaction, activities and organizing, thanks to its basic features such as widespread usability and access.

Social 買粉絲working websites such as Facebook and MySpace have created a new form of socialization and interaction. Users of these sites are able to add a wide variety of items to their personal pages, to indicate 買粉絲mon interests, and to 買粉絲nnect with others. It is also possible to find a large circle of existing acquaintances, especially if a site allows users to utilize their real names, and to allow 買粉絲munication among large existing groups of people.

Sites like meetup.買粉絲 exist to allow wider announcement of groups which may exi
