Here’s a hint: On a recent episode of Apuesta por un amor (shown are stars Roberto Palazuelos, Paty Manterola, and Juan Soler), Soledad was drugged and date-raped in a Mexico City hotel room. That’s right, the hottest network this summer among the coveted 18-to-34 group isn’t Fox — it’s Univision. The Spanish-language network is averaging 1.2 million viewers in the age group every night, 50,000 more than Fox. The strategy is simple: night after night of new programming. ”We’re capitalizing on a youth-oriented audience intensely involved in programming that isn’t [reruns],” Univision VP David Wolfson tells Entertainment Weekly’s Timothy Gunatilaka in the upcoming issue. While other nets are airing repeats, you can join the growing legion of fans of telenovelas like Apuesta por un amor (”Gambling on Love”), which airs at 8 p.m. every weeknight. Smoldering glances and the battle of the sexes are understandable in any language.
