Hashtag movements are social media campaigns that use a specific hashtag to raise awareness about a particular issue or cause. These movements often gain traction on platforms like Twitter, Instagram, and Facebook, allowing users to share their thoughts, experiences, and support for the cause. The hashtag serves as a rallying point, making it easier for people to find and engage with related content. Examples of popular hashtag movements include #BlackLivesMatter, which advocates for racial justice, and #MeToo, which addresses sexual harassment and assault. These movements can mobilize communities, influence public opinion, and even lead to policy changes by amplifying voices and fostering discussions around important social issues.
