Content Choice and Selective Reporting Media as today's main information sources unarguably have the power to influence political agenda-setting and public opinion. They decide which topics and issues are covered and how they are reported. Still, in many cases those decisions are not primarily determined by journalistic criteria, but affected by external factors. The importance of shareholders forces media to generate more profit every quarter, which can chiefly be raised by enlarging audiences and hence attracting more advertising money. Therefore the focus of media's programming in many cases shifts towards audience alluring content like entertainment, talk-shows, music and sports. Further pressure regarding the selection of content occurs from advertisers and marketers, who often implicitly or explicitly suggest to refrain from programming which could show them or their products and services (e.g. tobacco) in an unfavorable light. Interlocking directorships and outright ownerships can moreover be responsible for a selective coverage. Financial connections with defense, banking, insurance, gas, oil, and nuclear power, repeatedly lead (commercial) media to the withholding of information, which could offend their corporate partners. In totalitarian regimes also pressure from political elites may be a reason for the suppression or alteration of certain facts.

1950: The Turing Test Alan Turing, an English mathematician and logician, advocated the theory that eventually computers could be created that would be capable of human thought. To cut through the long philosophical debate about exactly how to define thinking he proposed the "imitation game" (1950), now known as Turing test. His test consisted of a person asking questions via keyboard to both a person and an intelligent machine within a fixed time frame. After a series of tests the computers success at "thinking" could be measured by its probability of being misidentified as the human subject. Still today Turing's papers on the subject are widely acknowledged as the foundation of research in artificial intelligence.

skytale The skytale (pronunciation: ski-ta-le) was a Spartan tool for encryption. It consisted of a piece of wood and a leather-strip. Any communicating party needed exactly the same size wooden stick. The secret message was written on the leather-strip that was wound around the wood, unwound again and sent to the recipient by a messenger. The recipient would rewound the leather and by doing this enciphering the message.
