How TV Viewership is calculated?

Universe            The Total/Actual number of people in a defined target audience.
Reach
  • Number of individuals from the universe who are exposed to the medium or vehicle
  • Reach is normally expressed in Percent terms
Calculation of Reach            Universe: 10 individuals.
            For a single episode of Chhoti Maa:
            if out of the above 10 people 6 saw atleast 1 minute of the programme then,
            Reach:6 out of 10
            Therefore, reach = 60%

Variations of the reach concept

  • Gross Reach
  • Cumulative Reach
  • Net Reach
Gross Reach
  • Gross Reach = Summation of all audiences who have been exposed to the vehicle
  • Week 1 : 1000
  • Week 2 : 2000
  • Week 3 : 1500
  • Week 4 : 1200

    Hence, Gross Reach = ?
    1000+2000+1500+1200=5700
