Ted Koppel has joined the Discovery Channel to make news documentaries, bringing his former top producer and eight other ex-"Nightline" staff members, the cable channel announced Wednesday.
Koppel will host and produce long-form programming examining major global topics and events exclusively for Discovery, said network President Billy Campbell. … Koppel will also conduct some of the town hall-style meetings that were a staple of "Nightline" programming, Campbell said.
