How did we start?
• From industrially funded research project to profitable commercial software house via the last dot-com meltdown…
VNC project, 1994 – Open sourced, 1998 – Research lab closed, 2002 – Company incorporated, the following day

Life in 1994• Yes we had ftp, Archie and Gopher• But these were the domain of academics and
a few large IT centric organisations• 1991 CERN starts World Wide Web project• V1.0 Mosaic was released in 1993 • Altavista appeared in 1995• Google didn’t even exist – it only started as a
research project in 1996 and was incorporated as a company in Sept 1998

Network evolution• ARPANET was the US military network since the 60s, some limited
commercial use in the early-80s when TCP/IP emerged in 1983• In 1991 Al Gore passed the High Performance Computing and
Communications Act• The “Information Superhighway” is born• In the UK JANET (the Joint Academic Network) and Super JANET were
the pioneering networks• In 1993 Super JANET deployed 14 sites linked by 34Mbps ATM network
connections• By 1995 London, Bristol, Manchester and Leeds had all been connected
with 155Mbps links• Today all major UK cities joined by 10 & 40Gbps
links, redundancy, high availability and reliability
• Fibre to the home will soon be a reality……………

But, what were networks like for the mere mortals?• Large commercial companies were lucky to have a
1Mbps network connection, costing a fortune ~£20K pa
• For most companies it was modems:19K2, 56K or 2B+D ISDN (128K)
• Links really were low data rate, slowconnection set-up, high latency and unreliable
• As an aside - last week, Cablevision has just announced the introduction of 100Mbps to 5M homes in New York, with uncapped usage for $99 per month

It was a world of promise• Computing power was accelerating• Graphical interfaces were appearing• Media rich, bandwidth hungry applications were
proliferating• Everything looked great………….
• But, in 1994 life was still hard• Networks were poor• The VNC project was formed to address the key issues
of working with rich data across poor networks, whilst maintaining acceptable usability

embryonic Internet• It is characterised by variable coverage, intermittent
connections, relatively low data rates and high latencies
• VNC set out to address these issues 15 years ago for the desktop. With hundreds of millions of users VNC is the de facto standard for desktop remote control
• The VNC Mobile Solution is the choice for secure cross platform mobile remote control
