Dow Jones: Univision has postponed plans for a 2015 initial public offering due to the lackluster recent performance of media-company stocks and a sluggish market for first-time share sales. The Spanish-language broadcaster’s board met on Thursday and discussed the issue, and chose to leave its options open for a debut early next year. Univision, which went private in the leveraged-buyout boom that preceded the financial crisis, initially had plans to launch its IPO shortly after Labor Day.
