After decades on air (he joined the BBC in 1989), legendary broadcaster Robin Lustig has signed off.Lustig's last edition of the BBC NewsHour was broadcast this morning at 9 am Eastern. And after a fun retrospective (which you can hear on the BBC website), he ended the show. And in that sign off, Lustig mentioned his listeners here in Louisville, a city he visited a few years ago. Those of us who were able to meet with him during his day in Kentucky were treated to a great discussion on global affairs and the practice of journalism.
