A almost complete absence of control Within modern markets such as exchanges, control systems are very stringent. They focus on the design of systems, their operation, their integrity and the absence of abuse in the use of data. Each of these controls is assigned to a separate institution and whose control is the only activity. For example the control systems engineering computing prices can be assigned to control a company or an international technical audit firm recognized. Strangely, control practices for audience measurement beyond these rules. The controls are organized as part of committees often people who participated in the selection of the device, or close to them. Technical assessments are not assigned to companies of technical control or audit firms whose job it is, but individual experts whose methods lack rigor. Their actions are not frequent.
