A couple of Twitter tips to thank for the ”Nightline” throwback video embedded below — and this one truly is a defining moment about decency and what can and cannot be said about race and sports. It was on this day exactly 23 years ago that Dodgers executive Al Campanis told anchor Ted Koppel (who is at his best in the 2-minute clip) about the difference between blacks and whites, as he sees them. His comments triggered such backlash that the once-beloved baseball man lost his job. To be honest, we had no plans to acknowledge this 23rd anniversary. But Tweet handle @KenColeman1967 – Detroit Charter Commission member Ken Coleman – did, who at 1:55 a.m. sent this tweet: On this day in 1987, Al Campanis, L.A. Dodgers executive for more than 40 years, resigns after making raciel remarks on ABC’s “Nightline.” And, then, just about an hour ago, another Tweet, this one from @metcalfer, offering a similar recognition. So we did a quick search of the ABCNews.com archives and here it is, from April 7, 1987. Click HERE to read a fuller Wikipedia history.
