Comparing the use of two DiTV transmission services: same service, different outcomes

NHS Direct Digital was available to almost exactly the same number of users in both Hull and London via two different transmission DiTV companies: Kingston Interactive Television (KIT) and HomeChoice. This paper employs metrics based on server generated logs to compare use and user differences between the two services. Server logs that record user activity on a real‐time and continuous basis were made available and used to make comparisons between the two services. The data were collected for both services over a similar period, February 2002 to May 2002. During this period the NHS Direct Digital service was visited by approximately 3,000 people and more than 5,000 NHS Direct videos were viewed. Making the study probably the largest analysis of health videos ever conducted.
