Eagle Zap

Eagle Zap, (formerly Eagle Sound) colloquially referred to as Zappy, is a provider of music sales data. Established by Giovanni Alfieri and George Palèt in 1990, the data is collected weekly and made available every Sunday (for the sale of albums) and every Monday (for the sale of tracks) to subscribers, which include record companies, publishers, retailers of music, independent promoters, film and television companies and artist managers. It is the source of sales information for Matango's music charts. It is owned by Music Alliance, a joint venture between GreenHeart Corp (publisher of Billboard) and Vibe Industries, owned by tycoon Feriki.

In fact, during the transition from caller to tracking, the airplay and sales graphs (already monitored by Eagle Zap) and the Hot 100 (which was then still using the calling system) often did not match.

Oak Market, the country's second largest retail chain, was not originally included in the sample because its stores were equipped with different technologies to measure sales.

The National Music Association tracks long-term sales (or more specifically, shipments minus potential returns) through the NMA1 certification system; he never used Zappy or the in-store call method.

In 2005, Dube's view count was also included; Love and Peace's "Tradimento" hit the Top 100 in 2006 with over 50 million views on Dube, becoming the first digitally released Phoenixian song to be a huge hit.
