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". The term webcasting usually refers to 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.
Webcasting is also 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.
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.

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 from Apple, they launched the Macintosh New York Music Festival from July 17–22, 1995. This event audio webcast concerts from more than 15 clubs in New York City. Apple later webcast a concert by Metallica on June 10, 1996 live from Slim's in San Francisco.
In 1996, Apple webcast the Recording Academy Grammy awards.
In January 1997, the launch of UK NetYear was webcast from London. Managed by Chelgate, it was the second webcast in the UK, the first being a David Bowie concert some months earlier. The UK NetYear webcast was only watched by a handful of people, although it was also simultaneously broadcast by satellite from London to Glasgow, Cardiff and Belfast, and to 23 schools around the country.
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.
The first[which?] 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..
A notable webcast took place in September 1999 to launch NetAid, a project to promote Internet use in the world's poorest countries. Three high profile concerts were to be broadcast simultaneously on the BBC, MTV and over the Internet: a London concert at Wembley Stadium featuring the likes of Robbie Williams and George Michael; a New York concert featuring Bono of U2 and Wyclef Jean; and a Geneva concert.
More recently, Live8 (AOL) claimed around 170,000 concurrent viewers (up to 400 kbit/s) and the BBC received about the same (10 Gbit/s) on the day of the 7 July 2005 bombings in London. The growth of webcast traffic has roughly doubled, year on year, since 1995 and is directly linked to broadband penetration.
Connecting Media was one of the first companies to do live webcasting using a special IFP Van (Internet Field Production) dedicated to webcasting.
Today, webcasts are being used more frequently and by novice users. Live webcasts enable the viewing of presentations, business meetings, and seminars etc. for those that telecommute rather than attend. Such sites offer live broadcasting as an affordable alternative to attending physical public speaking events expanding the viewing audience to anyone that has an internet connection. Other live webcasts are held completely online independent of any offline component. Webcast content network sites can enable users to find content that interests them by searching the site.
Live sporting events, both local and national, have also quickly become frequent webcast subjects. With regard to smaller events such as Little League, amateur sports, small college sports, and high school sports, webcasting allows these events to have full audio or video coverage online when they may not be able to book standard radio or TV time. Websites like Meridix Webcast Network, Texas Sports Radio Network, SportsJuice, and others allow local schools, teams, and broadcasters to produce their own webcasts, which also have the advantage of being accessible to anyone with an internet connection (i.e. relatives several states away), unlike the range and market limitations of terrestrial radio and TV.
Virtually all major broadcasters now have a webcast of their output, from the BBC to CNN to Al Jazeera to UNTV in television to Radio China, Vatican Radio, United Nations Radio and the World Service in radio.
Origins of the term
"Webcasting" was first publicly described and presented by Brian Raila of GTE Laboratories at InterTainment '89, 1989, held in New York City, USA. Raila recognized that a viewer/listener need not download the entirety of a program to view/listen to a portion thereof, so long as the receiving device ("client computer") could, over time, receive and present data more rapidly than the user could digest the same. Raila used the term "buffered media" to describe this concept.
Raila was joined by James Paschetto of GTE Laboratories to further demonstrate the concept. Paschetto was singularly responsible for the first workable prototype of streaming media, which Raila presented and demonstrated at the Voice Mail Association of Europe 1995 Fall Meeting of October 1995, in Montreux, Switzerland. Alan Saperstein (Visual Data, now known as Onstream Media (Nasdaq:ONSM), was the first company to feature video webcasting in June 1993 with HotelView, a travel library of two minute videos featuring thousands of hotel properties worldwide.
On November 4, 1994, Stef van der Ziel distributed the first live video images over the web from the Simplon venue in Groningen. 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.
The term webcasting was coined (in the early/mid 1990s) when webcast/streaming pioneers Mark Cuban (Audionet), Howard Gordon (Xing Technologies), William Mutual (ITV.net), Craig Schmieder (Applied Media Resources) and Peggy Miles (InterVox Communications) got together with a community of webcasters to pick a term to describe the technology of sending audio and video on the Net… that might make sense to people. The term netcasting was a consideration, but one of the early webcast community members owned a company called NetCast, so that term was not used, seeking a name that would not be branded to one company. Discussions were also conducted about the term with the National Association of Broadcasters for their books — Internet Age Broadcaster I and II, written by Peggy Miles and Dean Sakai.
…DataWeb News had done an in-depth on it not two weeks ago, and tourists had been trekking up into the New York hills ever since the webcast.
A wedcast is a webcast of a wedding. 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.
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 lead to a recent increase in this phenomenon.
