In one aspect, an example method involves accessing first data representing a program schedule of a media program; making a determination that first text of the program schedule matches second text displayed by a teleprompter, where a portion of the media program was recorded proximate a time when the second text was displayed; using the first text of the program schedule as a basis to select a portion of the program schedule; and responsive to at least the determination, storing data indicative of a correlation between (i) the selected portion of the program schedule and (ii) the recorded portion of the media program. An example non-transitory computer-readable medium and an example computing device, both related to the example method, are also disclosed herein.
