Below the Line illuminates the hidden labour of people who not only produce things that the television industry needs, such as a bit of content or a policy sound bite, but also produce themselves in the service of capital expansion. Vicki Mayer considers the work of television set assemblers, soft-core cameramen, reality-program casters, and public-access and cable commissioners in relation to the globalized economy of the television industry. She shows that these workers are increasingly engaged in professional and creative work, unsettling the industry's mythological account of itself as a business driven by auteurs, manned by an executive class, and created by the talented few. As Mayer demonstrates, the new television economy casts a wide net to exploit those excluded from these hierarchies. Meanwhile, television set assemblers in Brazil devise creative solutions to the problems of material production. Soft-core videographers, who sell televised contents, develop their own modes of professionalism. Everyday people become casters, who commodify suitable participants for reality programs or volunteers, who administer local cable television policies. These sponsors and regulators boost media industries' profits when they commodify and discipline their colleagues, their neighbours, and themselves. Mayer proposes that studies of production acknowledge the changing dynamics of labour to include production workers who identify themselves and their labour with the industry, even as their work remains undervalued or invisible.
