How has capitalism changed since Marx first wrote his critique, and how can Marxism be applied to these changing circumstances? As capitalism has expanded into a global system and frequently melded cultural and economic production into one entity, the conclusions suggested by Marxist theory have likewise shifted with the target. And although the world has changed in unforeseen ways, the underlying economic structure has remained capitalist, allowing for a continuous evolutionary trajectory of critique linking Marx to present-day theorists such as Fredric Jameson. The writings of Marx, the Frankfurt School, and Jameson are examples of the different Marxist critical responses to the three stages of capitalism and collectively demonstrate the tropes common to all stages of capitalism. They testify to the commodification and integration over time of the cultural and economic, while providing an interpretive framework by which to judge the present conjunction of culture and economics and the possible future alternatives presented by the Internet.
