Ten or more years ago there was some type of regulation regarding the sound volume of TV commercials whereby sponsors were not to increase the sound volume when commercials ads were aired. If this ever was a ruling it certainly has expired or is just ignored by TV broadcasters. It is very evident that when commercials come on the volume is much higher than the program. This burns me to have to have the remote in hand to adjust the volume each time a commercial comes on and adjust when the program resumes. If you agree lets all contact the FCC or whomever might have some control on this problem.
