In the US, my experience correlates with the rise of TNT and cable television - Ted Turner bought the rights to show certain films on his new cable channels and “Shawshank” got heavy rotation. It was akin to “background noise” sometimes. Others can probably recall the frequency.
Based on a Stephen King short story, I’m a fan. Never did catch “The Majestic” and no interest. Ebert was a national treasure, great share.
