Not long ago an essential component for selling a house was a "TV room." Now, the TV room is disappearing. "The modernist architects would say that a house always responds to the technology that is introduced," said James Moustafellos, associate director for the Center for Design + Innovation at Temple's Fox School of Business. "In some ways, it is no different than the advent of central heating or air-conditioning. When most of the heat in a house was from a central fireplace or other outlet, families lounged together in one room. Once heat was everywhere in the winter or coolness was everywhere in the summer, they could disperse."
