While I've been a medallion member of one tier or another for the last 20 years, I was never a member of the Frequent Flyer program that preceded SkyMiles, so there are a lot of people here with a longer history than mine.
MQM boosts went into effect with the introduction of the DL branded AMEX cards.
In the early days of the original Delta Frequent Flyer Program, AMEX spend on Delta counted toward MM status. Sadly, my employer gave me a Diner's Club card for travel. The DC card spend DID NOT count toward MM status.
Also in those days, minimum mileage credit was 1000 miles per segment. I DID benefit from that! ^
