Oh come on.
Nobody on air was unprofessional. Whatever the result there was a good chance it would be the top story, and its not often working in news broadcasting that you get to follow a happy story. I've worked on news stories whilst big sporting events are going on- if you're fortunate you get to take a moment to look at a replay or penalties in a shootout etc. That reaction (and more) would have been replicated in groups of people in all sorts of places, I'm glad those in the newsroom got the chance to enjoy it.
In the process it created an enjoyable bit of TV too. Ross handled it really well (I'd expect nothing less).
What if a Columbian viewer tuned in only to find a world renowned news organisation cheering for their loss. Ever think about that?
Had it not been simulcasted to the World it'd be more appropriate IMO.
I think a sensible Columbian viewer would have realised it was an English / British broadcaster and understood their happiness, unlike some of the griping here.
