It's been a long time coming, but commercials are finally getting toned down.
So there you are, watching your favorite show. You're really invested in the plot that's unfolding – the main character is going through some sort of emotional trauma and you're on the edge of tears. Then bam, a commercial comes on that's so loud it jolts you out of your mood. Commercials are interruption enough, but when they're significantly louder than the show you're watching, they can be downright infuriating.
The Commercial Advertisement Loudness Mitigation Act, otherwise known as CALM, is in effect as of today. This requires that ads be brought down to a level that's manageable and won't blow out your eardrums unexpectedly. The CALM act has no influence on the quality of ads though, so expect more talking babies and anthropomorphized animals.
