I guess they found a loophole. I noticed they very much like to put a commercials right before the show ends, and after it ends they put another one. There's also tons of previews of their own shows (i guess that don't count as commercials) weidly sandwitched between commercial blocks - and that could alternate for a long time. Maybe something like that.

I remember debacle about the volume of the commercials, stations tend to put them up much louder than shows, so people were getting blasted with decibels out of nowhere, this was forbidden too, so they also circumvented that by some kind of sound frequency trick so the commercials are still perceptively louder than shows.

Or maybe they just are ignoring it altogether, polish television regulating organ is very slow and blind unless international scandal blows in their faces.
