The element of marketing mix involved when a vendor supplies newspapers from house to house and across the streets is "place". Place refers to the various channels, locations, and methods used by a company to make its products or services available to customers.

This is an important aspect of the marketing mix as it ensures that the product is available where and when the customers need it, which can help to increase sales and customer satisfaction.
