What you need to knowInstagram's Head, Adam Mosseri, stated on Threads that a new test will rollout on Instagram for its home tab. Mosseri states that Reels and DMs drive the most growth on Instagram, so this test is to see if users vibe with the changes. Instagram is reportedly rolling out a test overseas that aims to put its short-form content front and center much quicker. Scrolling down would drop you into the classic Reels feed, which just has you scrolling through the short-form, vertical content. Mosseri states, "Reels and DMs have driven most all our growth at Instagram over the last few years, so we are exploring making them the first two tabs."
