Completely ignoring parts of PA, WV, DE, and NC... there are about 5 million "households" in the MD / VA area. I've seen estimates as high as 90% for the percentage of households that pay for some form of cable / satellite TV.
For the purpose of being conservative, let's consider that estimate grossly over-inflated... do you think at least 50% of households pay for something more than rabbit ears? So you're looking at a minimum of 2.5 million subscribers in the MD / VA region that pay a fee to MASN every month... regardless of how much they watch the channel(s). Fees go down as you move away from the base market, so come up with a number less than $2 if you'd like to account for averaging. Monthly means you multiply by 12 for annual gross revenue.
Now consider that if the 90% figure is more accurate, you're looking at 4.5 million subscibers in just MD / VA... at 12 payments per year. That's 54 million "iterations" of subsciber payments.
Then throw in the outlying areas I've ignored. Then throw in likely modest contributions from satellite carriers. Then throw in whatever advertising dollars they ARE pulling in at present... even with low ratings. Then consider that MD and VA both rate well above the national average for income (which translates in to a wealthy market, and more advertising potential).
It's either a cash cow just like Peter Angelos predicted it would be (helping them improve the Orioles on the field)... or they're mismanaging it terribly and wasting gobs and gobs of untapped resources.
