Since debut, SM Entertainment has created two subgroups for Super Junior. The intentions of the subgroups were part of SM Entertainment's strategy to not limit Super Junior's activities;^[56] the goal of this strategy was to show that Super Junior could do more than just singing one kind of genre of music but a whole range like dance, ballad, trot, hip hop, etc.

At some concert appearances, the members have been witnessed sectioning themselves off into smaller-groups, and each performing its own set of songs. This causes speculation that the group's strategy is to actively target particular musical tastes. As these smaller groups are rarely permanent, the constantly shifting makeup of these groups is able to target as many possible "tastes", and by evaluating which groups were well received, a clearer evaluation of the market tastes is possible and obviously these groups will enjoy reappearances in later Super Junior concerts.

On April 2007, six members of Super Junior, Yesung, Kang-In, Sungmin, Donghae, Ryeowook, and Kyuhyun were featured in the soundtrack of the MBC drama H.I.T. They sang both the opening and ending theme, titled "Success" and "H.I.T" respectively. There has been speculation that these six members would be forming another subgroup, but this never happened
