Throwback Thursday, commonly abbreviated as #TBT, is one of the most enduring social media trends, gaining massive popularity on platforms like Instagram and Twitter in the early 2010s. The concept involves users sharing nostalgic photos or videos from their past, ranging from childhood memories to events from just a few years prior. While its exact origin is debated, it became a cultural phenomenon that allows people to reflect on personal growth, fashion faux pas, and historical moments. Today, it serves as a weekly opportunity for brands and individuals alike to engage their audience through the power of nostalgia and shared experiences.
