"Instagram Threads Surges to Top 10 as X Drops to No. 36 in December Downloads"

Instagram Threads saw a significant increase in downloads in December, reaching the top 10 most downloaded apps across both the App Store and Google Play. The app's growth has been attributed to Meta's advertising push and its move into the "fediverse." Meanwhile, Instagram became the most downloaded app in December, surpassing TikTok, which has faced criticism for its e-commerce push. In contrast, X, the company formerly known as Twitter, saw a decline in downloads, indicating ongoing challenges following its rebranding.
