WOW series

"WOW" is a series of annual compilation albums featuring contemporary Christian music dating from 1995. Comprising songs submitted by each partner label, the annual WOW Hits releases are usually double CD sets. The series was officially cancelled in 2019. Throughout its run, the WOW franchise evolved into one of the most successful collections of Christian music.

Background
The birth of the WOW record project can be traced to Grant Cunningham, A&R Director at Sparrow Records. In November 1994, Cunningham made a business trip to EMI Limited in London, which at the time was the parent company of Sparrow Records. There, he noticed that several British record labels were issuing an annual CD of top-rated songs, known as the NOW series, containing collections of pop songs. Cunningham brought the idea back to Sparrow. Sparrow executives suggested a similar project be developed for Christian pop music and he was assigned the task of getting the project off the ground.

Released in late 1995, WOW 1996 was the first in the WOW Series and the first recording put together by the three major Christian record companies of the time: Word Records (now Word Entertainment), Sparrow Records (formerly part of EMI Christian Music Group), and Reunion Records (now part of Sony's Provident Label Group). Still today, after each submitting label agrees to a reduced master royalty, the final decision on the tracks to be included is made by committee. Production, marketing, and distribution for the "WOW Hits" series was handled by EMI Christian Music Group, and from 2013, by Capitol Christian Music Group, which is now a Universal Music Group company.

In 1999, the annual WOW Worship series was launched. Rather than using the year, each release is identified by the color of the cover. The worship series and hits series are today among the best-selling members of the product brand. Beginning in 2008, WOW began releasing separate single-disc collections spread throughout each year, rather than a two-disc collection toward the end of each year. In addition to WOW Hits, which focuses on the most popular pop and pop-rock music, plans call for either single-disc WOW Rock Hits and WOW Pop Hits collections released twice a year.

WOW Series
WOW Series was the first and most successful series of WOW collections, and contains the following albums:

Wow Hits
In 2000, the WOW Series was rebranded to WOW Hits, forming the second and also the most successful series of WOW collections. In 2008, the WOW Series contemplated releasing three single discs per year instead of the annual double discs customers were used to. Only one single disc was ever released, WOW Hits 1. in the spring of 2008, before reverting to the annual format. It is not known why the publishers decided to return to the annual format instead of the new format, which was inspired by the Now That's What I Call Music! series, which releases three discs annually. It contains the following albums:

WOW Gospel
WOW Gospel are released annually, beginning with WOW Gospel 1998. The focus of this series is gospel, and the compilation has been issued every year since 1998.

For instance, New York, NY was honored due in part to the September 11, 2001 tragedy, and so on. The exception is WOW Gospel 2009 in which the United States of America was honored due to the previous year's election. Another exception was when Atlanta was honored twice - first in 2007 and 2013.
