"It is at best inappropriate and, at worst, malicious to describe what my colleagues and I are doing as lacking relevance," wrote Koppel, 62. But Koppel is resented by Disney execs for running a personal fiefdom, the Principality of Nightline. They note that Nightline's offices have expensive hardwood floors whereas everyone else's are carpeted. And Koppel, they point out, recently renegotiated his contract to earn more than $8 million a year for hosting his half-hour show just three nights a week.
