iQIYI launches a new horizontal-screen, short-form suspense drama brand called Undercurrent Theater, debuting with the series “Dead of Winter.” Multiple reports say the title quickly gains traction with audiences and tops charts soon after release.

the announcements present the move as part of iQIYI’s broader content expansion into suspense-focused, short-format viewing designed for horizontal screens. PR Newswire frames the launch as a strong debut for China’s online entertainment platform, emphasizing the speed of audience uptake. The Hindu and Business Line likewise highlight the same branding and debut title, focusing on the suspense slate expansion and the series’ early chart performance rather than additional production or distribution details.

Overall, the outlets converge on the company, the new brand format (horizontal-screen short-form), the debut title (“Dead of Winter”), and the reported early success, while offering limited specifics beyond the launch and performance claims.
