The one thing I have notices in the last 10 years is the MASSIVE increase of the number of Christian music stations. They are in every major city of the USA (I travel alot). Also the Christian music is top rate - as good as any rock and roll. With the mix of music they play, plus the promise of music that families can listen to without diving for the dial - they are getting hugely popular. I hear them in banks, restaurants, etc. If you didn't know the song - you would just think it was any music radio...definitely a bright spot in movement of this nation. And a very "slick" advertising campaign for Jesus.
Devil's advocate: I'm not sure Jesus needs or wants slick advertising. Its a long stretch to derive the need for "slick advertising" from the Bible's Great Commission.
