I believe that no the Wilmington metro area (New Castle, Cecil, and Salem counties) are not included in the Philly RADIO market, but are included in the Philly TV market. That's why Philly is #8 in radio, but is # 6 or something in TV. That 600,000 potential listeners from the Wilmington Metro Area is missing from the Philly radio market. What I've never understood is why Kent County isn't included in the Wilmington market. I don't believe they're included in the Salisbury/Ocean City market, so that would mean there listening habits aren't tallied by Arbitron.
Let's back up here and remember why radio ratings, and thus "radio markets," exist in the first place.
Why do commercial radio stations need to know how many people are listening to their programming? Because they need to be able to tell advertisers how many listeners will hear their advertisements.
Measuring listenership costs money. If you're a PPM market, you have to recruit listeners to wear PPM meters, provide encoders to stations, collect and process all that data, and so on. If you're a diary-based market, you have to find diary participants, print diaries, mail them out, interpret and input the data, and so on. Arbitron doesn't do any of this out of the goodness of its heart. It's a business, too, and it only spends the money to conduct ratings surveys in areas where it knows its customers will pay for that data.
Arbitron first began collecting ratings data back in the days when AM was king, and the markets it surveyed then tended to be a little more compact than they are now, in large part because so many of those smaller AM signals didn't go very far. (There was a time when signals like WHAT and WDAS AM were actually competitive players in Philadelphia, after all!)
In some exceptional cases, Arbitron eventually merged small nearby markets when FM signal coverage completely changed the game. Dallas and Fort Worth were separate markets until 1970, each with their own roster of small-coverage AM signals. That 30-mile gap between the two cities became irrelevant when big class C FM signals started signing on that blanketed both markets, and in 1970 the broadcasters in both cities voted to combine the markets.
They didn't have a state line between them, the way Wilmington and Philadelphia do, and Wilmington and Philadelphia never got the massive commercial development between the two cities that Dallas and Fort Worth did. (Imagine if PHL airport was located somewhere in Chester County and had two million people living and working within ten miles of it. That's what the Arlington area between Dallas and Fort Worth is like.)
So back to the existing market lines: those are the areas where stations in Philadelphia and Wilmington, respectively, believe they have enough signal penetration and advertiser support to make it worth paying Arbitron to conduct ratings surveys.
If Philadelphia radio stations felt they had enough at stake to make it worth incorporating New Castle County into the Philadelphia market, and they wanted to pay Arbitron to do it, it's possible that Wilmington could become an "embedded" market - there would still be a separate Wilmington book, but New Castle County numbers would also figure into the Philadelphia book. (There are several such "embedded" markets around NYC - Middlesex/Somerset/Union, Nassau/Suffolk, "Hudson Valley.")
The fact that they don't do this tells you that Philadelphia stations don't think there's enough ad revenue at stake from Wilmington to make it worth the expense.
If Wilmington's stations felt that they had enough at stake to pay to have Kent County surveyed, they'd ask Arbitron to do so. In the AM days, the Wilmington AMs didn't really cover Kent County at all, and that set a marketing pattern that has continued into the present.
With TV, obviously, it's a somewhat different story, inasmuch as there is no local TV for Wilmington...
Back in the early 1950's, Wilmington had its own TV market as WDEL-TV originally on channel 7 was on the air, apparently I believe from somewhere I read that WAMS actually had a request for a permit to have a TV station also. At some point in the 1950's the Wilmington TV market was lumped in with Philly's. WDEL-TV went to channel 12 due to complaints of interference with NYC and DC channel 7's. Then WDEL-TV lost the NBC-TV affiliation due to Channel 3, I believe there calls were WPTZ in Philly complaining to NBC about having another NBC-TV affiliate so close. Interestingly WDEL didn't lose the NBC radio affiliation. This lose of NBC-TV programming also with the demise of the DuMont TV network kind of ended WDEL-TV's real chance to be a player in the TV game, (no reruns back in those days and not much else available for an independent station to air) as they eventually sold the TV station and in 1958 ended Wilmington's days of having a commercial TV station as Storer Broadcasting's WVUE-TV went dark. In 1963 WHYY became channel 12 and the rest is history. By the way, Storer still uses the WVUE-TV calls in I believe New Orleans.
Under Storer, channel 12 tried to become a Philadelphia-market station. It moved to a new tower in Glassboro NJ and bought land in Roxborough with the intention of relocating there.
I don't believe Storer ever owned the New Orleans WVUE (and the company hasn't existed, anyway, in about twenty years.)
There was also a construction permit for WILM-TV in Wilmington on channel 83.
