A new personalized channel called "Videos You Might Like" collects videos that may be of interest to you. As you scroll through the Explore grid, you may also see "Featured" channels with videos on specific topics.
The more you like, the better Explore gets, adjusting to your preferences and showing you more of the stuff you enjoy. And if you see something you don’t like, tap “See Fewer Posts Like This” in the ‘…’ menu to make your Explore experience even better.
The new Explore features are only available in the United States to start. Instagram has plans to bring them to the rest of world soon.
You can download Instagram from the App Store for free.
