I don't need to look it up. I'm talking from experience. I own 1000s of VHS that I still watch regularly. Collect movies of all formats. And my dad always collected them, too. Always been around the VHS, and a lot of it. In fact, a lot of my collection now was his collection, I got those when he passed away.
What exactly do I need to look up? That you need to put a head-cleaner in your VCR if it's eating tapes? Absolutely common knowledge for anyone familiar with VHS.
What exactly makes you believe that it has a shorter shelf life? Plastic takes forever to degrade. And the plastic shell is there to protect the film inside.
Let me clear here, I'm not arguing that VHS is a better format that DVD or Blu-Ray. Obviously VHS has the lowest picture quality (except for maybe video-CD). Just about the reliability comment. They're solidly built and will last you your entire lifetime as long as it's not exposed to moisture, extreme temperatures, or magnets. And the data can't be chipped or scratched away as long as you aren't opening up your tapes and getting violent with them.
Honestly, these formats really haven't been around to get solid data. As of now, the first VHS, CD, or DVD made should all still run and play just fine as long as it's kept properly. I have VCD Discs (older than VHS), that still run and play just fine. I have records and 8-tracks that still play fine. And most of us have Atari carts that run a-okay. I don't think it's a problem we're really gonna run into in our lifetimes, with the way people like us keep our collections in good shape.
