I haven't seen the ad in question, but yeah, the LDS church has put on paid advertising in the past. I used to see more of it when I was young, but
I rarely see it at all anymore. That might be connected to me watching more TV when I was young, too, though
No conspiracy here, in my opinion, though being LDS I'm obviously biased

Still, I think it's just a simple advertising plan. It's a waste of
money, in my opinion, though; everyone these days knows who Mormons are. This wasn't always true, and advertising on TV used to make more sense, but
nowadays I can't remember the last time I had someone who said they'd never heard of Mormons.
