Peter Liguori, who built the News Corp-owned FX cable network into a powerhouse and later, as COO of Discovery Communications, oversaw the launch of Oprah Winfrey's cable network, will become CEO of Tribune Co. when it emerges from bankruptcy, the Chicago Tribune and the Los Angeles Times (both Tribune-owned newspapers) reported on Saturday, citing sources familiar with the situation. Although best known for its newspaper business, Tribune's principal revenue is generated by its 22 television stations, including WGN Chicago (and cable superstation WGN America), KTLA Los Angeles, WPIX New York, WPHL, Philadelphia, KDAF Dallas, and WDCW Washington DC. On Friday, the FCC granted waivers to the new Tribune ownership group, allowing them to continue to operate duopolies -- TV stations and newspapers in the same city. Liguori would replace Eddie Hartenstein, who also had an extensive broadcasting background when he came to Tribune in May of last year. (He had been a founder and longtime chairman and CEO of home satellite service DirecTV.) Hartenstein, in turn, had replaced another broadcaster, radio exec Randy Michaels, who resigned in 2010 amid accusations of sexual misconduct. In a statement on Friday, Hartenstein said that the FCC's action in granting the waivers will enable Tribune to continue moving forward toward emergence from Chapter 11, a process we expect to complete over the course of the next several weeks.
