Many people would keep the manuals near the TV, so they could remind themselves how to use the rarely used features.
The Panasonic VCR we had included a barcode reader in the remote. The printed TV guide has barcodes for each program. This interface was very easy to use -- scan, and press "transmit".
Edit to add a link to an advert: https://www.youtube.com/watch?v=tSGUbE1v5RA -- the sheet of timecodes was necessary if you didn't have a TV guide with them printed, as shown here: http://www.champagnecomedy.com/panasonic-barcodes-saving-you...
That's the outrageous point. You shouldn't need manuals for operation of ordinary domestic appliances! If you do then you automatically know its design is substandard!
(The only reason you should need a manual is for some info or maintenance function that's not normally associated with its user-operated functions.)
So now my wristwatch is sitting on the desk.
*The hard part of programming the Beta(and early VHS) for me was getting the family to leave the tuner on the channel I/we wanted to record.
