The impressive viewership figures, reported by Deadline, mark a significant milestone for the show, representing a 25% increase over the 3.2 million viewers who tuned in for the Season 3 premiere. This robust start suggests that 'The Gilded Age' is not only retaining its audience but actively expanding it, building on the momentum of previous seasons. For context, HBO noted that the third season went on to average a substantial 8.8 million U.S. viewers per episode, setting a high bar for the current run.

Season 4 plunges deeper into the intricate social landscape of 1880s New York, exploring the consequences of Bertha Russell's audacious ascent into high society. Her family must now navigate the repercussions of her ambition, while Agnes van Rhijn, ever the formidable matriarch, seizes an opportunity to reclaim her family's esteemed position. Meanwhile, Marian embarks on a new personal journey, and Peggy faces the challenges of gaining acceptance from her future in-laws, all against a backdrop where every desire comes with a price.

The new episodes of 'The Gilded Age' are broadcast weekly on Sunday nights at 9 p.m. ET/PT on HBO and are available for streaming on HBO Max, with the season finale scheduled for December 20.
