Actually, long before then, Washington’s Channel 9 was known as WDMV-TV, which stood for “the District, Maryland and Virginia.” But WDMV died long before the current vogue for “the DMV” (the call letters live on at a small AM radio station in Walkersville, Md.).
That is just an awful error that should have been caught by editors or by Farhi himself. Seriously, there are things called search engines. Unbelievable.
By the way, I don’t like the term DMV, I much prefer BeltwayLand. I’ve been using it for 15 years. It works much better.
