In the United States came up with a switch for advertising
Magnavox TV Volume Regulator
If you decide to find another television sound control that would look as depressing and depressing as the Magnavox TV Volume Regulator, you will have to suffer a lot. But the device has excellent quality: it can distinguish advertising from a television show. And not just to distinguish, but also turn down the volume of commercials or even turn them off.
Devices of this kind were released earlier: it is well known that commercials go on television with a higher sound level than movies and broadcasts. However, all consoles that use volume as the main criterion for advertising recognition had an important drawback: the prolonged screeching of the talk show host, accompanied by stormy applause from the audience, could lead to the TV program being turned off by a naive machine.

Unlike its predecessors, the Magnavox TV Volume Regulator uses a more sophisticated work algorithm, which allows to distinguish the commercial from the loudest show or concert with high accuracy. The company Magnavox (known to be the first in the world in 1972 to release the Odyssey game console, three years ahead of the famous Atari Pong system) describes it as follows: the console analyzes the sound level several thousand times per second and instantly equalizes the sound if detected sharp drops. However, the possibility of independently setting the maximum volume level, which reduces expression in the performances of singers, and in the passionate dialogues of the stars of Latin American TV shows, is preserved for especially nervous TV viewers. TV Volume Regulator is already available in online stores for $ 49.95.
