Castells' theory on the networked global society

In sociology, the idea of a networked global society highlights how modern capitalism has evolved, particularly through the role of information and technology. This concept comes from the work of Manuel Castells, a Marxist sociologist who examines changes in Western societies during what he calls the late-modern period of capitalism.

Key features of late-modern capitalism according to Castells

Castells argues that information has become the primary resource in today's capitalist systems.

Shift from vertical to horizontal communication

In the past, communication and information flowed vertically in society. This meant that capitalist elites controlled the flow of information, passing it down to ordinary people.

However, Castells suggests that digital technology has transformed this setup. Now, information and communication are organised horizontally. This occurs because digital tools, like social media and blogs, are widely accessible. As a result, everyday individuals can organise politically and influence the world of politics using platforms like social media, Twitter, and blogs.

Decentralisation of power through digital technology

A key outcome of this horizontal organisation is the decentralisation of power. Digital forms of communication empower ordinary people by placing more control in their hands.

The concept of media convergence

Media convergence is a process driven by digitalisation, which refers to the conversion of information into digital formats that can be easily stored, shared, and accessed. This development has blurred the lines between different types of media, creating new ways for information to be combined and distributed.

How media convergence combines information types

Media convergence allows various forms of information to be integrated into a single system. This includes text, photographs, videos, films, voices, maps, emails, music, and social networking features.

This integration happens through digital devices like smartphones or laptops, which serve as all-in-one delivery systems.

Interconnectivity between social media platforms

Media convergence also enables different social media platforms to interact and share data. For example, users on one platform can link to content or contacts from another, such as when Facebook users view updates from their Instagram connections.

Key characteristics of social media

Social media represents a core element of the digital age, transforming how people communicate and share information globally. It is defined as a participatory culture, meaning a network of websites and applications that encourage users to actively engage, create, and collaborate.

Core features of social media as a participatory network

• Content creation and sharing - Users can generate and widely distribute their own material.
• Social networking - Platforms allow people to build relationships by creating public profiles and inviting others to connect and share messages, news, experiences, photos, and videos.
• Spread of news and experiences - Information can be shared quickly among users.

Devices used for social media access

Social media is typically accessed via digital devices such as computers, tablets, and smartphones.

Global spread and examples of social media platforms

The rise of social media has been marked by its swift expansion worldwide, with billions of users adopting various platforms. This growth reflects the networked nature of modern society, where digital tools connect people across borders.

Key examples of social media platforms (2017 user figures)

• Facebook - The world's largest social networking site. It had over 1.9 billion registered users worldwide, with users in the USA spending more time on it than any other website.
• LinkedIn - A professional networking platform focused on career development, where users share professional skills to find work opportunities. It had over 500 million users globally.
• Twitter/X - A microblogging service. It had approximately 330 million users worldwide.
• Snapchat - A mobile app. It had approximately 180 million active users.
• WhatsApp - A messaging app. It had over 1.1 billion users in 180 countries.
• Instagram - A photo and video-sharing app. It had 650 million users.
