Systems, methods and media for purchasing and commenting on identified products in streamed media are provided. In one example, a method comprises receiving program content and data describing program content from a content source and identifying product-related metadata associated with the program content. The product-related metadata includes data relating to one or more products or services displayed in the program content. In one embodiment, the program content is communicated to a display device for presentation to a first user in the display device. User commentary is received from a second device and communicated to the first user while the first user is viewing the program content. Commentaries of other users, for example in a wider social group, can also be presented to the first user.
