It’s dinnertime in South Korea. Thousands of people are tuned into the Diva, a petite doe-eyed woman wearing a baggy t-shirt. In front of her is an enormous spread of food: salad, chicken wings and chunks of lobster bobbing in a vat of red stew. She could be entertaining guests at a dinner party, except for the fact that her guests are tuning in online, via the video streaming platform AfreecaTV. As she takes a bite of chicken, she answers questions about the taste and cost of the food, sampling each dish and proclaiming them all delicious.

This is a “mok-bang”, or “eating room”, the voyeuristic trend of watching people eat online.
