Step-by-step explanation:
It is true that changes in technology have helped activist groups grow since the 1970s. The advent of new technologies, particularly digital communication tools like cell phones and the Internet, has transformed the way activists organize, disseminate information, and execute campaigns. In recent history, social media and smartphone technology played crucial roles in the coordination and success of large-scale protests like the Arab Spring. Activists were able to rapidly share plans and updates, gain global support, and relay unfiltered news to the world, thereby empowering citizens and challenging government-controlled narratives. The intertwining of social movements with technology has continued to evolve, providing activists with powerful tools to effect change in the present day.
