The term “TRP”, associated with TV shows, stands for

Audience measurement is the branch of media research that turns viewing behaviour into a number an advertiser can buy against. Its basic unit is the rating: the estimated share of a defined universe of viewers who were tuned to a particular channel or programme during a particular interval. Ratings matter commercially because airtime is priced off them.

Applied to Indian television, that rating unit is reported as Television Rating Points, abbreviated TRP. The underlying data comes from people meters fitted in a statistically drawn panel of households: each meter logs which channel the set is tuned to and which household member is present, and the panel readings are projected to the whole viewing universe. BARC India has run this measurement since 2015, and TAM/INTAM ran it earlier. A programme with a higher TRP is estimated to reach a larger share of that universe, so its slot commands a higher advertising rate.

Reading the three near-miss expansions against real media-research vocabulary shows where each of their qualifying words actually belongs:

• Total Rating Points — the aggregate-exposure figure advertisers actually work with is Gross Rating Points (GRP), computed as reach multiplied by average frequency across a whole advertising schedule.

• Time Rating Points — time is handled through dayparts and time-band reporting (prime time, afternoon, late night), which segment the day rather than forming a separate points metric.

• Thematic Rating Points — theme is handled through genre classification (news, general entertainment, sports, music), the axis on which viewership tables are grouped.

So the expansion of TRP in the television context is Television Rating Points.
