Netflix created a challenge-style campaign with a custom filter, hashtag, and sound to promote the show. TikTok star Dexter Mayfield was part of that campaign, and said that as soon as the ad was re-posted by Netflix and promoted in the app, it took off. The 15-second video of Mayfield dancing currently has over 47 million views and the #SelenaNetflix hashtag has since accumulated over 4.7 billion views.

But then others started participating in the challenge, too.
