Explainer
Reddit's recent surge in popularity, overtaking TikTok as the fourth most visited social media site in the UK, highlights a significant shift in user behavior and preferences. According to Ofcom, the proportion of UK internet users engaging with Reddit has increased by 88% over the past two years. This growth is particularly notable among Gen Z users, who are increasingly seeking out platforms that provide human-generated content, contrasting with the algorithm-driven nature of TikTok. The change suggests that users may be prioritizing authenticity and community-driven discussions over the more curated content typically found on other platforms. As three in five online Brits now encounter Reddit, this trend could have implications for how social media companies approach content creation and user engagement strategies moving forward.
