Webcast
A webcast is a media presentation distributed over the Internet using streaming media technology to distribute a single content source to many simultaneous listeners/viewers. A webcast may either be distributed live or on demand. Essentially, webcasting is "broadcasting" over the Internet.
The largest "webcasters" include existing radio and TV stations, who "simulcast" their output through online TV or online radio streaming, as well as a multitude of Internet-only "stations". Webcasting usually consists of providing non-interactive linear streams or events. Rights and licensing bodies offer specific "webcasting licenses" to those wishing to carry out Internet broadcasting using copyrighted material.
Overview
Webcasting is used extensively in the commercial sector for investor relations
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]
The term "webcast" had previously been used to describe the distribution of Web or Internet content using conventional broadcast technologies such as those intended for digital video (
History
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.[5] 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.[6]

On February 6, 1999, a 21-minute Victoria's Secret fashion show featuring supermodel Tyra Banks aired exclusively on Broadcast.com. The webcast was promoted by a 30-second television spot during Super Bowl XXXIII and drew an estimated 1.5 million viewers.

Wedcast
A webcast of a wedding may be called a wedcast;[24][25] 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, where it would be expensive or difficult for people to travel to see the wedding in person.[24]
On August 13, 1998, the first webcast wedding took place, between Alan K'necht and Carrie Silverman in Toronto Canada.[26][27]
The first webcast teleconference 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.[28]
Webcasting a funeral is also a service provided by some funeral homes.[29] Although it has been around since at least 2005, cheaper broadband access, the financial strain of travel, and deployments to Iraq and Afghanistan have all led to increased use of the technology.[30]
