Benny Fine (born March 19, 1982) and Rafi Fine (born June 9, 1984) known on YouTube as The Fine Brothers (currently known as Fine Brothers Entertainment) are two online producers, and writers who are known for their successful React video series Kids React, Teens React, Elders React, YouTubers React & Adults React, their several timed spoiler series, narrative web series, as well as creating the first transmedia sitcom on YouTube, MyMusic. The Fine Brothers have been creating content online since 2004, and have found success on YouTube where their main channel, TheFineBros has over 2 billion video views and 13 million subscribers. The Fine Brothers also have a secondary channel, under the name TheFineBros2; which they launched on May 14, 2009. The secondary channel has accumulated over 679,000 subscribers. They release behind the scenes content, as well as clips from their news podcast "All We Know" on the secondary channel. They preformed in Annoying Orange. On July 27, 2014, The Fine Bros released a new channel called REACT, which houses new shows for the stars of the React videos (Kids, Teens, Adults and Elders).

In 2016, the Fine Brothers have been criticized ever since they copyrighted React, which means no other YouTuber can make reaction videos. In one week, their subscriber count reduced from 13M to 12.5M. They later apologized, but some of their new videos still have more dislikes than likes to this day, which will take some time to recover from the criticism.
