  1. Media and Estimates of Audience Size

  2. Demands of IMP • Greater importance on accurate and detailed target audience description • Move from national to local • Move from mass to targeted media • Move from demographics to lifestyle segments • Too much information on media patterns of different targets from market to market • Narrowcasting takes time and expertise

  3. Budgetary Constraints • Clients are more tuned-in • Biggest part of advertising budget • Negotiability of new media create substantial time and billing demands • Turf wars between and within IMC departments, and with clients

  4. Accountability • Explosion of new media creating greater demand for accountability • Get beyond subjective evaluation toward concrete comparisons • Started creating medium specialists • Bottom line: • Still mainly about cost efficiency

  5. Changing Role of Media Planners • More client contact and consulting • Must become account people • Must know who are the pioneers • Must be versed in IMC elements • Including promotions and direct mail • Must be grounded in fundamentals

  6. Key Concepts • Universe: The whole to which each subset is related • Ex. Total TV Households • Rating: Percent of the total universe that is or does something • Ex. Watch “Survivor”

  7. Understanding Ratings • Total TV Households = 105.5 MM • Survivor Viewing Households = 22.5 MM • Rating: Survivor HH related to TV HH

  8. Calculating Ratings • Rating: % of TV HH tuned to a program • Survivor Viewers / Total TV HH = Rating • 22.5MM / 105.5MM = 21.3

  9. Decimal Point Placement • In Media Planning, Decimal Point Placement is Very Important • Million (MM) vs. Thousands (M or 000) • 105.5MM TV HH = 105,500(000) TV HH • Percentages converted from raw number • Survivor Rating = .213 = 21.3%

  10. HUT = Households Using Television Ex. How many HH were watching TV from 7:00 - 8:00 on Thursday? 65.5MM HUT Level: Viewing HH related to TV HH Rating: Survivor HH related to TV HH HUT Level: % of TV HH watching television at a specific time HUT / TV HH = HUT Level 65.5MM / 105.5MM = 62.1% Calculating HUT

  11. Rating: % of TV HH tuned to a specific program HUT Level: % of TV HH watching television at a specific time Share is different Share: % of TV HH tuned to a specific program among all Households Using Television Survivor Viewers / HH Using TV = Share 22.5MM / 65.5MM = 34.4% Calculating Share

  12. Formulas • Rating = HUT x Share • Share = Rating / HUT • HUT = Rating / Share • Rating = Audience Size / Universe • Audience Size = Rating x Universe • (Audience size = Gross impressions)

  13. Gross Impressions • In media, primarily concerned with accumulation of audience • Each audience member exposed to the message is considered an “impression” • Summed to equal “gross impressions” • Audience size = gross impressions for single show • For multiple programs, add audience sizes together for total gross impressions (GI)

  14. Gross Rating Points • Same logic applies to rating points • Rating for individual programs are added together to calculate the total rating points accumulated across a schedule • Gross Rating Points = GRPs Ex. Rating for Program 1 + Rating for Program 2 + Rating for Program 3 Gross Rating Points

  16. Duplication of Impressions • 159.7 GRPs and 168.8mm GI • More than 100% of the Universe? • How is this possible? • GRPs and GI allow for the duplication of impressions • Someone might see more than one ad • Survivor and X-Files or multiple X-Files
