How measurement practices have changed over decades
Launch library · evergreen read

Early measurement in the profession relied heavily on simple counting: column inches, minutes of airtime, the raw number of mentions secured across a given period. These counts were relatively easy to gather quickly but said very little about whether any of that coverage actually changed anything meaningful for the audience or the organisation behind the original story.
As the profession gradually matured, measurement shifted steadily toward assessing genuine quality and effect rather than volume alone, incorporating tone, message pull through and eventually real shifts in audience awareness or perception, reflecting a growing recognition that more raw coverage did not automatically mean more effective communication for the organisation involved.
This evolution continues today as new channels generate entirely new kinds of data to interpret and understand properly. The underlying question, however, has remained remarkably consistent throughout this whole history: not simply how much attention was generated in total, but whether that attention moved an audience any closer to genuinely understanding, trusting or acting on the organisation's intended message.
