My feeling is this is an Americanism. Here in the UK I've been to church events in the past - usually stuff linked to school events (harvest, nativity etc), or weddings/funerals, and been in a few old cathedrals which have a donation box, but the stuff I see on US TV shows like the Simpsons -- collection plate passing, advertising, televangelism, etc all seems very different and far more obviously "con artistry"
There is some cult that does some low-key advertising in the UK (occasional posters on bus stops in London) over the last decade or so, the alpha church or something, which is mildly concerning, but the general course of religion, from what I can tell it's just a place some people go and have a chat and a sing-song, no different to the pub really.
