An information infrastructure is defined by Ole Hanseth (2002) as "an awesome shared, evolving, open, standardized, and heterogeneous installed base" and by Pironti (2006) as all of the people, processes, procedures, tools, facilities, and technology which supports the creation, use, transport, storage, and destruction of information.
The notion of information infrastructures, introduced in the 1990s and refined during the following decade, has proven quite fruitful to the "information systems (IS) field. It changed the perspective from organizations to networks and from systems to infrastructure, allowing for a global and emergent perspective on information systems. Information infrastructure is a technical structure of an organizational form, an analytical perspective or a "semantic network.
The concept of information infrastructure (II) was introduced in the early 1990s, first as a political initiative (Gore, 1993 & Bangemann, 1994), later as a more specific concept in IS research. For the IS research community an important inspiration was Hughes′ (1983) accounts of large technical systems, analyzed as socio-technical power structures (Bygstad, 2008).
Information infrastructure, as a theory, has been used to frame a number of extensive case studies (Star and Ruhleder 1996; Ciborra 2000; Hanseth and Ciborra 2007), and in particular to develop an alternative approach to IS design: "Infrastructures should rather be built by establishing working local solutions supporting local practices which subsequently are linked together rather than by defining universal standards and subsequently implementing them" (Ciborra and Hanseth 1998). It has later been developed into a full design theory, focusing on the growth of an installed base (Hanseth and Lyytinen 2008).
Information infrastructures include the Internet, health systems and corporate systems. It is also consistent to include innovations such as "Facebook, "LinkedIn and "MySpace as excellent examples (Bygstad, 2008). Bowker has described several key terms and concepts that are enormously helpful for analyzing information infrastructure: imbrication, bootstrapping, figure/ground, and a short discussion of infrastructural inversion. "Imbrication" is an analytic concept that helps to ask questions about historical data. ""Bootstrapping" is the idea that infrastructure must already exist in order to exist (2011).
"Technological and non-technological elements that are linked" (Hanseth and Monteiro 1996).
"Information infrastructures can, as formative contexts, shape not only the work routines, but also the ways people look at practices, consider them 'natural' and give them their overarching character of necessity. Infrastructure becomes an essential factor shaping the taken-for-grantedness of organizational practices" (Ciborra and Hanseth 1998).
"The technological and human components, networks, systems, and processes that contribute to the functioning of the health information system" (Braa et al. 2007).
"The set of organizational practices, technical infrastructure and social norms that collectively provide for the smooth operation of scientific work at a distance (Edwards et al. 2007).
"A shared, evolving, heterogeneous installed base of IT capabilities developed on open and standardized interfaces" (Hanseth and Lyytinen 2008).
Accordion to the "Online Etymology Dictionary (OED) the etymology of the words that make up the phrase "information infrastructure" are as follows:
Information late 14c., "act of informing," from O.Fr. informacion, enformacion "information, advice, instruction," from L. informationem (nom. informatio) "outline, concept, idea," noun of action from pp. stem of informare (see inform). Meaning "knowledge communicated" is from mid-15c. Information technology attested from 1958. Information revolution from 1969.
Infrastructure 1887, from Fr. infrastructure (1875); see infra- + structure. The installations that form the basis for any operation or system. Originally in a military sense.
According to Star and Ruhleder, there are 8 dimensions of information infrastructures.
Presidential Chair and Professor of Information Studies at the "University of California, Los Angeles, "Christine L. Borgman argues information infrastructures, like all infrastructures, are "subject to public policy". In the United States, public policy defines information infrastructures as the "physical and cyber-based systems essential to the minimum operations of the economy and government" and connected by information technologies.
Borgman says governments, businesses, communities, and individuals can work together to create a global information infrastructure which links "the world's telecommunication and computer networks together" and would enable the transmission of "every conceivable information and communication application."
Currently, the Internet is the default global information infrastructure."
National Information Infrastructure Act of 1993 "National Information Infrastructure (NII)
The "National Research Council established "CA*net in 1989 and the network connecting "all provincial nodes" was operational in 1990. The "Canadian Network for the Advancement of Research, Industry and Education(CANARIE) was established in 1992 and CA*net was upgraded to a "T1 connection in 1993 and "T3 in 1995. By 2000, "the commercial basis for Canada's information infrastructure" was established, and the government ended its role in the project.
In 1994, the European Union proposed the European Information Infrastructure.: European Information Infrastructure has evolved furthermore thanks to "Martin Bangemann report and projects eEurope 2003+, eEurope 2005 and iIniciaive 2010 
The USAID Leland Initiative (LI) was designed from June to September 1995, and implemented in on 29 September 1995. The Initiative was "a five-year $15 million US Government effort to support sustainable development" by bringing "full Internet connectivity" to approximately 20 African nations.
The initiative had three strategic objectives:
