Continued investment in streaming contributed to a first-quarter loss for Spanish-language media giant TelevisaUnivision, which is seeing the bulk of its growth come from its Mexican operations while U.S. revenue stays flat with year-earlier results. Revenue during the quarter improved 7%, to $1.1 billion. Revenue from Mexican operations rose 23%, to $409 million. But revenue from U.S. businesses — a bigger part of the company’s overall financial results — stayed flat at $740 million, despite a first-quarter airing of a Spanish-only version of the 2024 Super Bowl on Univision.
