Islamic Revivalism - Question and answers

I've been researching both movements and have a basic understanding of their histories, but I'm struggling to analyze their contemporary strategies effectively. For example, I've read that Salafism focuses on textual purity, while the Muslim Brotherhood engages in political systems, but I need more concrete examples of how this plays out in real-world contexts like education, media, or social reforms. I'm also interested in how they adapt to issues like digital communication and globalization.
