Automated Measurement of Lineups

From Wikipedia, the free encyclopedia

AUTOMATED MEASUREMENT OF LINEUPS (AMOL) is the technology which allows Nielsen Media Research (NMR) to track an identification code within locally transmitted TV signals for network and nationally syndicated programs. NMR is also linked by computers to networks and syndicators in order to receive their latest schedule changes. Using this technology, NMR can pin down exactly what program was shown on what channel at a particular time.
