The unfortunate truth is that profanity is rampant, and not just on TV. Its hard to go out or even on the internet without seeing some sort of misuse of God’s name. In the past, I was guilty a few times, although a few times were unthinkingly.
But it is true its on many things on TV, and not just the R-rated material, but also sometimes in family films and in vintage films even from before the mid-60s in addition to otherwise harmless TV shows.
Something I do though is that (if I’m not already praying something such as a rosary while somebody else watches TV) whenever I hear His name mentioned in an irreverent manner in real life or on TV, I say a quick Glory Be.
