JerseyShor, you make an interesting point about WXHL (WVBH)'s approach to their format.
It mirrors a similar approach that many of the "popular" churches (that target the younger demos) are using today as well. They use very modern rock praise type music and tend to not use "preachy" sermon styles, but rather offer uplifting messages using video clips, music, jokes, almost a "G" rated monologue rather than a sermon (it feels very much like being in a Christian version of the Tonight Show rather than being in a worship service as rather than an organ and choir there is a praise band that really is a Christian Rock Band.
Many of these same churches will avoid "Church speak" religious sounding words, many will even avoid referring directly to the Bible or having bibles in the seats for people to use (these churches rarely if ever have pews), and don't refer to Bible texts in their sermons or if they do it is very low key. Many won't even have a cross or crucifix anywhere in the sanctuary. The pastor dresses in jeans or slacks and sports shirt rather than a coat and tie or a vestments (robes). For someone, like me, who's been a Christian for most of their life, it almost comes across like these churches and possibly a station format like WXHL is almost ashamed of their spiritual heritage.
On the other hand, they could simply be doing, what so many other parts of our society are doing these days, and that is "dumbing" down the message.
In WXHL's (WVBH)'s and this type of churches favor could also be, that as you said you're not religious and would possibly never listen to a "religious" radio station (and by implication you might also not ever darken the door of a church to attend a Sunday service), these "scaled back/low key versions" of Christian Radio and Church might be able to, in a limited way, present to you and other "unchurched" folks out there the Gospel message of Jesus Christ where you might never hear it otherwise. So, there's pluses and minuses for this approach to both Christian Radio and Church, depending on your point of view.
No matter what the viewpoint, it appears that WXHL (The Reach FM from Faith City Church in Christiana Delaware) has done rather well as they have repeaters and stations airing their programming all over the mid-Atlantic area into Ohio and other states ). Quite often those repeaters and stations are in markets where there isn't a Christian station at all or more probably there isn't a CCM (Contemporary Christian Music) formated station available. So WXHL fills a void in those markets.
Of course, as a non-comm their ratings numbers never show, but obviously, the people who listen are voting not just with their radio tuner, but with their wallet as WXHL isn't just a local CCM FM station in New Castle County Delaware, but has become a network of stations serving millions of listeners. It is very possible that WXHL actually has more listeners than any other Delaware radio station (even though most of those listeners may not live in Delaware).
