Archbishop Fulton J. Sheen praying the Rosary with his office staff:
When Archbishop Sheen was doing his television show in the 1950s, everyone in America watched it; Catholics and non-Catholics! He routinely received 15,000+ letters per day.

As a bonus, here’s a photograph (1948) of Archbishop Fulton J. Sheen speaking in Melbourne, Australia on the occasion of the 100th anniversary of the diocese there. (Cf. page 141 of Treasure in Clay: The Autobiography of Fulton J. Sheen.)
I believe that Archbishop Fulton J. Sheen was an amazing preacher and a holy man. It is true he had a bad period in the 1960s, but he came out of it before he died; you can tell by the lectures he gave encouraging everyone to make the daily holy hour. He gave these lectures all around the country, even when he was elderly and not in good health.
