Exactly one year ago today, the FCC passed a law banning producers from BLARING the volume of commercials. It goes into effect TODAY.

Here's the story from CNN:

Beginning Thursday, the Federal Communications Commission is barring broadcasters and pay TV providers from airing excessively loud commercials, saying ads must maintain the "same average volume" as the programs they accompany.

The move -- which undoubtedly will make many TV viewers happier, and save countless marriages -- addresses a problem that, regulators say, is almost as old as television itself.

Loud commercials have been a leading source of complaints to the FCC since its consumer call center began reporting top complaints in 2002.

Since January 2008, the FCC has received about 1,000 complaints and about 5,000 inquiries, the commission said.

Congress mandated the change in the aptly named Commercial Advertisement Loudness Mitigation, or CALM, Act in 2010. Last year, the FCC set a December 13, 2012, deadline for full compliance.

Until now, the FCC says it didn't regulate the "loudness" of commercials mainly because it was difficult to craft rules. For one thing, loudness is subjective.

WOO WOO! For once we can celebrate something the FCC did!
