   Castells examines global protest movements, such as the Spanish Indignados and the Arab Spring, to illustrate how ordinary people leverage social media platforms to organize, communicate, and exert influence on political processes. He details how decentralized networks enable rapid information dissemination, bypassing state-controlled media.

2. Media Framing and Public Opinion

   A significant section addresses how global corporations exert power by shaping information networks, controlling news coverage, and influencing regulatory policies to protect their interests in digital media ecosystems.
