Sentinel TV is an application which helps TV media planners to plan and monitor TV campaigns. Account managers can create campaigns for clients, planners can plan the TV shows depending on which advertisements would be shown as well as see the ratings for those TV shows based on broadcasting days, and to see the total planned budget. Furthermore, during the realization of these campaigns, the system gets the actual ratings and computes the realized budget spending, so that planners can monitor and adjust plans to fit the target client budget for the campaign.
