The invisible network

The history of the Internet is often told as a succession of brilliant inventions that changed everyday life overnight. However, available sources suggest a more complex and gradual reality. Between 1970 and 2009, the network was built layer by layer, first as a research tool and then as a communication space, before becoming the invisible infrastructure we take for granted today. This article examines the documented milestones of that period, distinguishing what sources confirm from what popular memory tends to exaggerate or simplify.

Origins in the Cold War

Sources indicate that the germ of the Internet dates back to 1957, in the context of the Cold War. Although this date is prior to the study period, it is fundamental to understanding the initial motivation for data networks. The idea of a computer network created to allow communication resilient to failures was the starting point. It was not a network for the general public, but a military and academic infrastructure. This distinction is crucial to understanding why the first users were researchers and not consumers.

The NCP protocol and ARPANET

In 1970, the first network control protocol (NCP) was developed. By 1971, 23 computers were connected to the ARPANET network. This data, documented in institutional sources, marks a concrete technical milestone. The connection of these machines was not a mass event, but a slow process of integrating academic and government nodes. The network was fragile, slow, and difficult to use, but it established the technical foundations that would allow future expansion. Evidence shows that technology preceded network culture.

The transition to TCP/IP

Although sources do not detail the exact date of the complete transition to TCP/IP in this period, it is a documented historical fact that this protocol became the standard. This transition was key to interoperability between different networks. Without a common protocol, networks would have remained as isolated islands. The adoption of TCP/IP allowed the network to grow beyond the limits of ARPANET, connecting universities, research centers, and eventually other institutions. This technical process is less visible than commercial milestones, but it is equally important for the history of the network.

The Internet in Spain

Specific sources on Spain indicate that the arrival of the Internet in the country was a gradual process. The use of modems that chirped when connecting and programs like Infovía are mentioned. These details offer a local perspective on the adoption of technology. Unlike global milestones, the Spanish experience was marked by the existing telephone infrastructure and regulatory policies. Evidence suggests that adoption was not uniform, but depended on the availability of resources and user training. The memory of the first Spanish users often focuses on the slowness of the connection, a technical aspect that reflects the limitations of the infrastructure of the time.

The web and massification

Although the web is a key component of the Internet, its development is later than the initial technical milestones. Sources mention the first domain and the first web image as historical milestones. These events marked the step from a text network to a multimedia network. The web made the Internet accessible to a wider audience, as it did not require advanced technical knowledge to navigate. However, it is important not to confuse the web with the Internet. The web is an application that works on the Internet infrastructure. This distinction is fundamental to understanding the history of the network and avoiding anachronisms in popular narrative.

Preservation of digital heritage

Since 2009, the Spanish Web Archive has collected and stored websites, blogs, forums, and images. This initiative is relevant to the history of the Internet because it allows reconstructing past uses of the network. Sources indicate that the preservation of digital heritage is an ongoing challenge. Many websites have disappeared, and with them, the memory of how the Internet was used in the past. The web archive is a tool to study the connection between people and services, allowing analysis of how usage practices evolved over time. This perspective is crucial for a complete history of the Internet, which should not only focus on technology, but also on network culture.

Limitations of the evidence

It is important to note that available sources have limitations. Not all dates and milestones are documented with the same precision. Some events are more known than others, and popular memory often distorts reality. For example, the idea that the Internet was born out of nowhere in the 90s is a simplification that ignores decades of technical development. In addition, sources may be biased towards certain aspects of history, such as commercial milestones, at the expense of more complex technical processes. A critical reading of sources is essential to build a precise and nuanced narrative of the history of the Internet.

Conclusion

The history of the Internet between 1970 and 2009 is a history of gradual construction, not of instant invention. Documented milestones show a complex technical and cultural evolution, marked by the transition from a research network to a global infrastructure. Available evidence allows reconstructing part of this history, but also reveals the limitations of digital memory. To understand the Internet of the past, it is necessary to look beyond the surface and examine the technical, social, and cultural processes that made it possible. This perspective not only enriches our understanding of the past, but also helps us reflect on the future of the network.
