The next installment of the longest-running telenovela in North America — Grupo Televisa SA versus Univision Communications Inc. — is coming to trial April 29 in Los Angeles federal court. And, as befits the interwoven backstories of plaintiff and defendant, it promises more fireworks than the Fourth of July and Cinco de Mayo combined.

Televisa, Mexico’s leading multimedia conglomerate, exports about 15 hours of prime-time programming to the U.S. each week. Univision, the U.S.’ leading Spanish-language multimedia conglomerate, imports this programming. At issue is the program license agreement, or PLA, dictating arrangements for content distribution and compensation.
