"an audio diary of his life"

History Art From Analog: 20 Years Of Voice Mail Makes A Movie:

"If there's one thing Mark Craig never did, it was hit "erase" on his answering machine. "When Craig got an answering machine in 1985, he wouldn't erase. He'd just replace the tape and throw the old one into a shoebox. Twenty years later, he had amassed hours and hours of what was, effectively, an audio diary of his life."

The resulting film is just twenty-three minutes but this has the potential to be a valuable social history archive.
