Reactions to “The Gilded Age” Season 3 finale flooded social media Sunday night, inspiring a level of FOMO for non-viewers and water-cooler conversation typically reserved for tentpole HBO shows like “The White Lotus” or “The Last of Us.”

The social media buzz has continued to rise for the drama series from Julian Fellowes, with Season 3 social conversation volume up 185% from last season and racking up double the number of engagements on the show’s social media posts, according to network data. Instagram and Facebook accounts surged by 188% season-over-season — twice the growth seen from Season 1 to Season 2.
