Mediabase is a music industry service that monitors radio station airplay in 180 US and Canadian markets.

Mediabase charts and airplay data are used on many popular radio countdown shows and televised music awards programs.

In January 1988, Mediabase began publishing a trade magazine known as Monday Morning Replay, featuring monitored airplay in the top 35 US radio markets.

Over the years, Mediabase has supplied data to numerous trade business-to-business (B-to-B) publications including Radio & Records, Network Magazine Group, Gavin, Hits, and Friday Morning Quarterback.

Published charts are used on popular business-to-business (B-to-B) and consumer websites including AllAccess, Friday Morning Quarterback, Country Aircheck, and Hits Daily Double.
