As far as WILM goes, "Elliot's in the Morning" is a good AM drive program. Bruce has a good sense of humor. His co-reporters are good. They bring the same news, as WDEL, it's more about the presentation of the product.
As I've said before WDEL's AM newscast is good and very professional sounding, with two excellent anchors in Melanie Armstrong and Peter McArthur, BUT they play at least one spot AFTER each item, so they do traffic, then a spot, then the weather, then a spot or two or three, etc, then a news story and then a spot. They play so many spots so often that it can take quite a while to hear what you tuned in to hear. It seems like 60 sec of info then at least 60 sec of spots/PSA's/Promos then another 60 sec of info then another 60 sec of spots, etc, then Melanie or Peter will tease you with what's coming up and then another 60 seconds of spots, etc, then another 60 sec of info and then another 60 seconds of spots, etc, etc. Frankly it gets irritating. As the old joke goes, "we'll interrupt these commercials for a news story". I've tried to listen to WDEL during morning drive, but the constant barrage of spots interrupting so often, is a turn off and causes me to switch to WILM.
WILM on the other hand traffic/weather together, then a block of spots, then some news story Bruce comes up with or a clip from The Colburn Report, so he gives you a chuckle as well as the serious news. His interviews with the various Fox reporters have improved greatly where he stays more focused on the news and less on trying to bash Obama or the Democrats so those are now better interviews, more news worthy. So bottom line is you get a reasonable amount of info before getting the next block of spots. Frankly it seems like WDEL and WILM are airing around the same amount of spots per hour, but WILM puts them into a block where WDEL gives you one or two every 60 seconds. To each his/her own. Plus the humor makes for a lighter start to the day, makes all that bad news a bit easier to hear first thing in the morning. I enjoy the Coburn stuff and look forward to it for my morning laugh while getting ready for work. So for AM drive, at least for my ears, WILM.
However, I would think as older more conservative type listeners listens to AM which might give WILM the advantage over WDEL during Al Messitti's Show. Even though Beck is Beck and a bit out there, conservative ears are not going to want to hear the liberal dialogue of Messitti, so they tune to WILM for Glenn Beck.
The one problem with Al's show is as working folks can't sit and hang on the phone waiting about 12-20 minutes to get on Al's show, he generally gets the same callers, most of whom are retired or unemployed. Because, when Al gets a call he'll have a nice long conversation with the person which brings him to the next 3-5 minute WDEL spot break along with the weather. If there's more than one caller a head of you, you're sitting for almost a half hour waiting to get your chance to talk to Al thus eliminating working folks from participating. If you're on a cell phone driving (hand's free of course heh heh) that's a lot of wasted minutes you're paying sitting on hold. Some of those callers are a bit boring which might also contribute to a gain for WILM.
Someone suggested placement of diaries being the issue. However, with WDEL vs WILM that's not likely an effect as WDEL gets out far better than WILM, even during the day, and at night no contest at all WDEL has it over WILM signal wise.
However, this is the first book in a while that WILM has beat WDEL, if it became a consistent thing, I'd then get worried at WDEL, but the fall book could just as easily have WDEL ahead of WILM. They both are not that far apart in ratings.
Another thing that might be helping WILM is their simulcast with WDOV in the AM drive so folks coming north from Dover or going south from Wilmington might remember WILM for the diary better than WDOV, even though they've switched to WDOV as they get below Smyrna and switch to either 1450 or 1410 depending on which way they are driving.
Shifting gears a bit. Maybe the Baltimore Oriole games have helped WWTX 1290 a bit to make up for losing the Blue Rocks and may be why they at least show at the bottom of the ratings. Baltimore has very polished radio sportscasters doing the play by play and they do give the score more often the the Phillies radio guys do and there are a fair number of O's fans here.
I didn't notice 89.7 WGLS showing up so the Blue Rocks may not be helping their ratings in the Wilmington area.
Also 1260 WNWK Newark shows at the bottom of the ratings too, which is a rare thing for the Newark station to show at all.
