Overview[edit] Webcasting is used extensively in the commercial sector for investor relations presentations (such as annual general meetings), in e-learning (to transmit seminars), and for related communications activities. However, webcasting does not bear much, if any, relationship to web conferencing, which is designed for many-to-many interaction.[1] The ability to webcast using cheap/accessible technology has allowed independent media to flourish. There are many notable independent shows that broadcast regularly online. Often produced by average citizens in their homes they cover many interests and topics. Webcasts relating to computers, technology, and news are particularly popular and many new shows are added regularly. Webcasting differs from podcasting in that webcasting refers to live streaming while podcasting simply refers to media files placed on the Internet.[2] History[edit] Webcasting is the distribution of media files through the internet. The earliest graphically-oriented web broadcasts were not streaming video, but were in fact still frames which were photographed with a web camera every few minutes while they were being broadcast live over the Internet. One of the earliest instances of sequential live image broadcasting was in 1991 when a camera was set up next to the Trojan Room in the computer laboratory of the University of Cambridge. It provided a live picture every few minutes of the office coffee pot to all desktop computers on that office's network.[3] A couple of years later its broadcasts went to the Internet, became known as the Trojan Room Coffee Pot webcam, and gained international notoriety as a feature of the fledgling World Wide Web. [4] Later in 1996 an American college student and conceptual artist, Jenny Ringley, set up a web camera similar to the Trojan Room Coffee Pot's webcam in her dorm room.[5] That webcam photographed her every few minutes while it broadcast those images live over the Internet

upon a site called JenniCam. Ringley wanted to portray all aspects of her lifestyle and the camera captured her doing almost everything – brushing her teeth, doing her laundry, and even having sex with her boyfriend.[6][7] Her website generated millions of hits upon the Internet, became a pay site in 1998, and spawned hundreds of female imitators who would then use streaming video to create a new billion dollar industry called camming, and brand themselves as camgirls or webcam models.[8] One of the earliest webcast equivalent of an online concert and one of the earliest examples of webcasting itself was by Apple Computer's Webcasting Group in partnership with the entrepreneurs Michael Dorf and Andrew Rasiej. Together with David B. Pakman

on June 10, 1996 live from Slim's in San Francisco.[9] In 1995, Benford E. Standley produced one of the first audio/video webcasts in history.[10] On October 31, 1996, UK rock band Caduseus broadcast their one-hour concert from 11 pm to 12 midnight (UT) at Celtica in Machynlleth, Wales, UK – the first live streamed audio and simultaneous live streamed video multicast – around the globe to more than twenty direct "mirrors" in more than twenty countries.[11][12] In September 1997, Nebraska Public Television
Television
started webcasting Big Red Wrap Up from Lincoln, Nebraska which combined highlights from every Cornhusker football game, coverage of the coaches' weekly press conferences, analysis with Nebraska sportswriters, appearances by special guests and questions and answers with viewers.[13] On August 13, 1998, it is generally believed the first webcast wedding took place, between Alan K'necht and Carrie Silverman in Toronto Canada.[14][15] On October 22, 1998, the first Billy Graham Crusade was broadcast live to a worldwide audience from the Raymond James Stadium in Tampa Florida courtesy of Dale Ficken and the WebcastCenter in Pennsylvania. The live signal was broadcast via satellite to PA, then encoded and streamed via the BGEA website.[16] The first teleconferenced/webcast wedding to date is believed to have occurred on December 31, 1998. Dale Ficken and Lorrie Scarangella wed on this date as they stood in a church in Pennsylvania, and were married by Jerry Falwell while he sat in his office in Lynchburg, Virginia.[17] Virtually all major broadcasters now have a webcast of their output, from the BBC

and the World Service in radio. On November 4, 1994, Stef van der Ziel distributed the first live video images over the web from the Simplon venue in Groningen.[19] On November 7, 1994, WXYC, the college radio station of the University of North Carolina at Chapel Hill became the first radio station in the world to broadcast its signal over the internet.[20][21] Translated versions including Subtitling

Wedcast[edit] A wedcast is a webcast of a wedding.[22][23] It allows family and friends of the couple to watch the wedding in real time on the Internet. It is sometimes used for weddings in exotic locations, such as Cancun and the Riviera Maya, Hawaii

or the Caribbean, for which it is very expensive or difficult for people to travel to see the wedding in person.[22] Webcasting a funeral is also a service provided by some funeral homes. Although it has been around for a decade, cheaper broadband, the financial strain of travel, and deployments to Iraq and Afghanistan have all led to a recent increase in this phenomenon.[24] See also[edit]
