It all started with PLATO…
Web conferencing is “the complete package.” Interestingly, the conceptual design
of web conferencing began long before the World Wide Web or Internet existed
structure in place. In the 1960s, the University of Illinois developed a system
known as PLATO for its Computer Based Education Research Laboratory (CERL). That
was a small, self-contained system that supported a single class of terminals
connected to a central computer. In 1972, PLATO moved to a new system of
mainframes that eventually supported over a thousand users at a time.
In 1973, Talkomatic was developed by Doug Brown. This was essentially the
first “instant messaging” program ever designed, with multiple windows
visualization of written notes in real time for several users simultaneously. In 1974,
Kim Mast developed Personal Notes, a new feature for PLATO that allowed
email for users.
In 1975, Control Data Corporation established its own PLATO system in Minneapolis,
Minnesota, the first commercial use of the multifunction conference system.
Within ten years, PLATO was being used at more than 100 sites around the world.
world, some with dedicated lines for full-time use.
However, by the late 1980s, microcomputers were becoming more reasonably
price and day of the week for mainframe based systems was over. eventually the
Control Data’s original systems were shut down because PLATO was no longer
economic. Control Data now has some systems operating under the name
CYBIS.
descendants of PLATO
In the late 1970s, Ray Ozzie and Tim Halvorsen worked at CERL. years later
took some of the features of PLATO and greatly expanded its
capabilities by designing one of today’s most powerful web conferencing tools
— Lotus Notes, released in 1989.
Lotus Notes was the first commercially released product that really took off.
to offer user-created databases, document sharing and remote location
communication under one umbrella. Created a “relationship-based” environment
that took the corporate world by storm.
Other descendants of PLATO included DEC Notes, originally known as VAX,

a universal web conferencing community. NetNotes is a client-server system.
designed to enhance the original DEC Notes, with WebNotes as a plugin for
Access to the World Wide Web.
True WEB conference
The distinction between true web conferencing and systems conferencing is
difficult, however, to define. When the Web first became a competitor as a
means of collaborative conferences with document exchange, etc., many companies
took conferencing packages originally designed for intranet systems and
redesigned them. The results were not always perfect. It was not until
In the mid-1990s, true reliable web conferencing software was available.
PLATO and other mainframe-based conferencing systems were based on a
centralized structure, with all elements feeding a central computer. This
structure saw the development of various types of conferencing software that
including Backtalk, Caucus, COW, Motet, Web Crossing, Podium, TALKaway, and YAPP.
PlaceWare, possibly one of the most influential web conferencing systems
developed, it had interesting origins in the 1990s at Xerox Palo Alto Research
Center, where it started as a multi-user game called LambdaMOO. PlaceWare was one
One of the first companies to provide full web conferencing after the
launch of PlaceWare Auditorium in 1997. In April 2003, Microsoft purchased
PlaceWare, adding it to its newly created Real-Time Collaborative Business Unit.
P2P changes the focus of web conferencing
Another popular form of software was Groupware, essentially defined by Lotus
Ratings. The difference between the centralized structure of PLATO based systems
and Lotus is in the extra features — Lotus provided a lot of other
options like scheduling and document sharing. Groupware software is more complex
than centralized software and focus on workflow; that is, make sure
documents, graphics and templates are where they belong. popular collaborative software
products developed in the 1990s included the InTandem, Livelink, Lotus Domino,
Oracle InterOffice, TEAMate and WebShare.
As the price of home computers fell, peer-to-peer (P2P) file sharing
became increasingly common on the World Wide Web, though mainly on
a user-to-user basis. That changed when members of the then-illegal Napster
informally organized group of university students and other music lovers, began
sharing millions of music files with each other. Started a revolution in the
Internet usage changing the way web conferencing was eventually
perceived. P2P started to be seen as the way to host web conferences, rather than
through a single server. .
Groove took this peer-to-peer concept and applied it to web conferencing. Tea
Groove technology, originally released in 2000, has been upgraded to real performance
power with Groove 2.1 in 2002 and it was impressive. The advantages of peer-to-peer
were immediately obvious: once you loaded the software and set it up,
never had to pay a subscription or user fee for an external server to store any
files, you’ll never lose all your files in one central location, and it’s set
and good for life (or until the next update, at least).
Another company that recognized the need for quality web conferencing
software during these years was WiredRed Software, founded in 1998. In 2003,
launched e/pop, a real-time web conferencing suite with
features for all aspects of the industry: it was the first installable web
conferencing software with no significant installation time.
NextPage also offers P2P web conferencing and document sharing capabilities.
developed out of the Napster movement. In fact, they use the example of Napster
file sharing and downloads to illustrate to businesses the benefits of using a
peer to peer network through a centralized server.
What about UseNet?
In the 1980s, Usenet software was developed with specific protocols for
format and transmit messages. It also allowed passing messages from one
news server to another, replicating around the world instead of being stored in
any location. It has become the standard for newsreaders on the Internet,
with Netscape Navigator and Internet Explorer, both with integrated newsreaders
for UseNet. .
For some, web conferencing can be achieved by simply taking advantage of
UseNet. Download free software to set up a news server, create some local
newsgroups on it, and have your users access your server with their web browsers
to create your conference site.
Most companies, of course, prefer to have a more professional package than
that, and ease of use and security are concerns best addressed with
companies that have specifically developed business or corporate web conferencing
solutions A good web conferencing package today contains voice over IP (VoIP),
co-browsing and app sharing at a minimum, with plugins and others
features if needed, including surveys, event management, PowerPoint
presentation, playback, recording and annotation and live marking.
Easynet, founded in 1994, is a European-based broadband network company
primarily providing European companies with web conferencing capabilities. This
infrastructure-based provider provides unbundled loop access to enterprises in
some countries as part of a “leased line” program for conferences.
VoIP is making noise
The latest frontier in web conferencing is the convenience of using IP-based systems.
voice communications on a regular basis with web conferencing. while web
conferences is considered convenient for the exchange of documents, text messages and
whiteboards and many other functions, many people still think that VoIP technology
it has poor quality overall, especially with so many people still using dial-up
connections .
Actually, there are several competitors in the market that have produced
excellent quality VoIP offerings in their web conferencing packages, including
Voxwire, Orbitalk, RoomTalk and VoiceCafe.
The future of web conferencing
One of the last obstacles to web conferencing has been the
incompatibility between Mac and PC. With the great preference for Macs by
those in heavy graphic industries such as architecture, advertising and
publication, it has always been difficult to share documents and establish
Web conferencing if the clients are PC based. .
WaveThree’s Session was released in 2003 to address this issue and it seems

first truly effective systems for Mac/PC collaboration over the Internet. Wearing
With a bandwidth of 128 KBPS or higher, Session provides video conferencing, desktop
share, share documents, whiteboards, and live annotations on photos and/or

horizon.
As web conferencing becomes more and more common, new developments
inevitably arise, including, perhaps, dedicated lines that are constantly open,
Enhanced and secure peer-to-peer access and more web conferencing options for Mac/PC.
With so many players on the field, there is bound to be a variety of
divergent developments in the coming years.
