Reply All did a great podcast about a woman who uploaded thousands of her photos to a company that then went out of business, and what happened after that. It’s a good listen and a transcript is available as well:

“Rachel was a faithful user of a photo storage website called Picturelife, until one day all of her photos disappeared. As she investigated, she realized that every Picturelife user was having the same problem. Alex tries to find out if there’s any hope of getting her photos back.”
