Media missteps

Viewed today on KNBC's morning show (Los Angeles, market #2): "arriagnment." Seen today on CNN: "apolgized." This type of sloppiness, though common and often the fault of the production department, lessens the credibility of a news department. I think it's fair to raise this issue -- if a station is careless about spelling, what else is it careless about? Facts? (As a former member of the media, I believe these types of mistakes are avoidable with a good set of checks and balances, and that's why they're worrisome when they happen.)
