You know the things - they pop up in the upper left corner of the screen at the beginning of the show with the age rating - from Y for kids to MA for “mature” audiences.
Was there some legislation that took effect on June 1 to make them bigger and more frequent? They seem almost double the size they used to be, and are being shown more often.
The TV ratings are a voluntary system adopted by the TV industry after Congress bullied them into it a few years ago. They’re not controlled by legislation. It’s likely that the industry-operated TV Parental Guidelines Monitoring Board, which sets the standards for these things, may have changed the specification.
IIRC, the icons are supposed to appear for 10 seconds at the beginning of the show and whenever the show returns from a commercial. As for the size, I don’t know.
Actually they’re only required to appear once at the beginning of the program and every hour thereafter (for anything that lasts longer than an hour.)
Of course some stations may show them more often if they feel like it.
From this site:
Thanks for the link - if nothing else it shows I’m not hallucinating! 
I want to chime in with “Its bigger and more Frequent” as well…
Why do they need to display the TV rating at all? Today’s cable & satellite boxes always contain the rating within the show description, which is but a single button-click away.
I wonder if this is secretly an anti-piracy measure, so if someone tries to sell a bootleg copy of The Simpsons, they can tell right away it was ripped from broadcast TV.
Because not everyone has cable or satellite.
