 To appeal to Hispanics and Latinos of all nationalities, the network soon instituted a policy of maintaining neutrality with its use of Spanish dialects, slang and humor on its domestically produced programs, enforcing program producers to limit the use of humor and slang relatable only to a specific Hispanic nationality.It also prohibited the use of English in its programming or advertisements (outside of product titles and dialogue featured in film trailers), most obvious in the use of Spanish equivalent placenames such as "Nueva York" rather than New York.In 1988, Blaya also substantially ramped up production of American-based programs on Univision's lineup, reducing the share of programming imported from Latin America (most of which came from Televisa) on its schedule.
