Reaction Video

Go To

It's kind of like Let's Play, but for videos. The host (usually called a "reactor") watches a video that they've never seen before, and we get to witness their first reactions to it. Some reactors also like doing predictions before they watch the video, or a quick analysis afterwards, but the main part is the reaction itself.

There are several channels on YouTube dedicated mostly to reaction videos (called "reaction channels"). They gather small, but dedicated fandoms, who enjoy watching their favorite reactor's reaction to different videos. Some of these reactors craft a specific persona they play on-camera, to make their reactions more interesting to watch. Their video choice usually involves a movie trailer, music video, viral video, rap battle, or Vine compilation.


Other YouTubers sometimes also make Reaction Videos; "Reacting to my old videos" is an especially popular theme.

Some reaction channels:

  • Akasan: A.k.a. The Black Man in Japan. A red-dreaded black man living in Japan, he likes to react to movie trailers, especially superhero-related ones, and K-Pop music videos.
  • BlastphamousHD

The former was founded by the two other original cast of FandomReactions, while the latter was founded by one of the previously mentioned duo with her boyfriend not too long after the girls parted ways. In both cases, the two spin-offs mentioned were founded by the twin sister of FandomReactions' leader, making the videos sister shows in both literal and figurative sense.

  • React: A series by The Fine Brothers that started back in 2010 and inspired most other YouTube reactors. Their videos feature several people reacting to one video, and then giving their opinions on it.

This series' popularity was most likely what inspired all other reaction channels on YouTube, even though none of them follow their exact formula.

Examples of this trope in media:

Live-Action TV

Professional Wrestling

  • Mick Foley shares an anecdote in his second book, Foley is Good, where ABC News showed him a video of some backyard wrestlers and asked for his reaction. Having been tipped off beforehand that they were going to show him some pretty horrific stuff, he said, "That looked like a lot of fun...but I have a feeling there's another video you're going to show me." They showed him the second video, and his response was to say that the kids in the video were being very unsafe and he did not condone any of it. When they broadcast it on TV, they showed the second video but his first reaction, "That looked like a lot of fun!"
