Most popular social media apps across top 10 economies. Huge dominance by Facebook (FB, messenger, WhatsApp and Instagram), Google has Youtube and Twitter in the list which is well expected. TikTok shows dominance in China and India, may expand its reach in other countries in upcoming months.
UPDATE: India has recently banned TikTok and other 100+ chinese apps due to the recent tensions between both countries but the ban came only after US intel issuing security vulnerability in TikTok and Apple also issued details about how TikTok used users clipboard information. So Tiktok can also be banned in the US very soon.
