Insurance companies and banks for one.
Once you've invested in the initial infrastructure (drives, libraries), the incremental cost of extra tapes isn't that much, so you can keep things on the shelf for a long time for not a lot of money.
Send to two tapes for resiliency and every few years to a tape-to-tape copy to stay on the latest hardware. LTO drives can read two generations back: the just-released LTO-9 stuff can read LTO-7 tapes, and also write LTO-8.
Though a lot of backup software supports S3 APIs, so some folks are sending (encrypted) bits to Amazon Glacier (Deep Archive) since they practically will never have to retrieve it.
