Understanding the “Most Watched Reel” Phenomenon
A “most watched reel” is not simply a viral video—it’s content that resonates so broadly and deeply it crosses boundaries of geography, age, and interest. These standout reels often:

- Keep viewers watching until the end.
- Inspire shares, comments, and saves.
- Align with ongoing trends, memes, or cultural moments.
