This article reports on an investigation to explore the possibility that ideology might be expressed in the treatment of corporate influence on federal government by social studies textbooks. Two textbooks were examined in the study--United States history and American government. Corporate influence involves activities that affect election and appointment of officials and policy decisions. Textbook content was analyzed for bias on the subject. Findings reveal ideological judgments and beliefs in the texts that provide support for corporate activities and economic arrangements conducive to corporate interests. Bias renders these textbooks inadequate for developing students' understanding of corporate influence on government.
