Methods, systems, and media for presenting media content items with aggregated timed reactions

A computing system comprising:

• a memory that stores instructions;
• and
• processing circuitry that executes the instructions to:
• determine whether a media content item is eligible for identification of key moments;
• responsive to determining the media content item is eligible for the identification of key moments, retrieve a plurality of reactions associated with the media content item, wherein each reaction in the plurality of reactions comprises a reaction timestamp that corresponds to a time within the media content item at which a reaction was received and a graphical icon that was selected from a plurality of graphical icons that each correspond to one of the plurality of reactions;
• group the plurality of reactions into a plurality of groupings based on the reaction timestamp and based on the selected graphical icon;
• identify a plurality of key moments within the media content item based on the plurality of groupings, wherein each of the plurality of key moments is associated with a representative graphical icon that corresponds to an aggregated viewer reaction;
• and
• cause an indication of the media content item to be presented in a user interface while presenting the aggregated viewer reaction at each time window associated with each of the plurality of key moments.

Non-transitory storage media comprising instructions that, when executed by processing circuitry, cause the processing circuitry to:

• determine whether a media content item is eligible for identification of key moments;
• responsive to determining the media content item is eligible for the identification of key moments, retrieve a plurality of reactions associated with the media content item, wherein each reaction in the plurality of reactions comprises a reaction timestamp that corresponds to a time within the media content item at which a reaction was received and a graphical icon that was selected from a plurality of graphical icons that each correspond to one of the plurality of reactions;
• group the plurality of reactions into a plurality of groupings based on the reaction timestamp and based on the selected graphical icon;
• identify a plurality of key moments within the media content item based on the plurality of groupings, wherein each of the plurality of key moments is associated with a representative graphical icon that corresponds to an aggregated viewer reaction;
• and
• cause an indication of the media content item to be presented in a user interface while presenting the aggregated viewer reaction at each time window associated with each of the plurality of key moments.
