birth date is usually taken to be 1985, when
the US National Science Foundation created
NSFNet, allowing universities access to five
supercomputer centres. Other networks
existed at that time (e.g. the UK’s Joint
Academic Network and CompuServe’s net-
working capabilities for corporate clients),
but NSFNet was TCP/IP enabled: it used
the protocols underpinning the Internet
today, directing ‘packets’ of data to computers
by assigning unique addresses to host
networks and machines (e.g. IP address
68.142.226.55 is yahoo.com).
The Internet emerged as a public utility due
to the popularity of the World Wide Web
(WWW) – a series of interconnected docu-
ments (web pages). This development is cred-
ited to Tim Berners-Lee, who fused the
concepts of hypertext (e.g. the ability to hyper-
link pages) with the architecture of the Internet
and developed the first web browser, in 1991.
Amazon.com began in 1995, the same year that
the Java programming language was integrated
with a web browser. Google started life as a
research project in 1996 – the year in which
Microsoft’s Internet Explorer was incorpor-
ated into Windows.Wikipedia, the free online
encyclopaedia (and invaluable resource for this
Dictionaryentry), was launched in 2001.
Clearly, the Internet and WWW have grown
rapidly in both use and scope. Whilst future
trajectories and their long-term socio-economic
effects are difficult to judge, recent history is
suggestive. The ‘dot.com bubble’ may have
peaked in 2000, but e-commerce (including
online banking and music downloads) is still
growing (e.g. downloads contributed 6 per
cent of total worldwide record sales in the
first half of 2005 – a 350 per cent increase in
value from 2004: http://www.ifpi.org)..) If cyber-
space develops as a dominant transaction
space, then undoubtedly it will impact upon
service- and retail-sector employment, and
perhaps also on the landscapes of commerce.
(Will the iconic ‘high street’ of shops and ser-
vices be threatened by e-commerce or benefit
as specialist shops are able to extend their
global reach?) The Internet also contributes
to alternative workspaces and practices, in-
cluding home-working and ‘hot-desking’,
and the collaboration of geographically sep-
arated persons in virtual meeting rooms and
e-seminars (technologies that are being used
to facilitate e-learning, taking traditionally
place-bound universities into global education
markets and ‘knowledge economies’).
It is likely that the WWW will continue to be
the primary point of access to more and more
information in online repositories, archives
and data warehouses. Who should control or
own this information? Google’s Book Search
facility allows the full text of books to be
searched but has involved digitizing the
book collections of some libraries, raising
copyright concerns amongst some publishers
and authors. Other parties may want to restrict
access to certain information for various
reasons, including anti-terrorist protection or
to close down undesirable websites. When
Google.cn was launched in 2006, Chinese
regulators required that ‘sensitive information’
be removed from its search results. This occa-
sionally happens in France, Germany and the
USA too (source: Google official blog).
Finally, whilst the Internet–WWW network
can confidently be predicted to expand, it is
unlikely to be perfectly ubiquitous. There are
digital divides globally in terms of communi-
cation infrastructures, as there are nationally
(e.g. broadband access is uneven across the
UK, generally to the detriment of rural
areas). Other geographies of cyberspace reflect
on who owns the various components of the
Internet–WWW (including IP addresses, con-
tent and service provision), raising social and
geopolitical questions (seegeopolitics). rh

interoperability The ability for something
to work or interface between separate oper-
ations or systems without error or changed
meaning. For example, digital downloads
from online music stores to portable storage
devices are facilitated by interoperability
standards such as MP3 audio compression.
The converse to interoperability is proprietary
data formats locking the user into particular
software. This was a problem with GIS,
addressed by the Open Geospatial (formerly,
Open GIS) Consortium leading the develop-
ment of standards for geospatial and location-
based services (www.opengeospatial.org) –
including the Geography Markup Language
(GML), a schema for the modelling, transport
and storage of geographical information. rh
