The meaning of the Panasonic "AG" prefix?
 

AG might be Panasonics company type, like Jvc Schweiz AG founded in Switzerland in 1968.

I doubt it. Very often these designations are inherited from Europe or Japan -- as diddly squat is made in North America -- and are nothing more than gibberish to us.

Panasonic and JVC are both owned by the Matsushita corporation. Sometimes we see overlap in the products. For example, the metal VHS-C adapters (example: CP7U) are available from both Panasonic and JVC. Nobody else has those; other companies have cheap plastic crap that usually ends with tapes being eaten due to tiny mm-width imperfections.

Panasonic wasn’t first to market with a video cassette recorder. They promoted time shifting, so automatic programmer for unattended recording.

Very interesting spokenward

A much better theory than I proposed
