Founded in 1916.  Mr. D.J. "Nick" LaRocca = Leader.

FIRST ever jazz record made by this band for both Columbia and Victor Records in 1917.

RESPONSIBLE for securing the name "jazz" (music style name) as we know it today.  
In 1917 the ODJB was responsible for securing the word JAZZ as a musical definition term.  Prior to the ODJB recording the music of the time was known as Ragtime and many other style names but not jazz.  There were three or four other groups that used the name jass within their band name dating back to 1914, but the term was used more in general language slang and was not used to describe a musical style until the ODJB secured it with their hit recording in 1917.

FIRST jazz band to sell over 1 million Victrola records worldwide within the year of its release.
-This event introduced millions of people worldwide to JAZZ for the very first time.-A popular but controversial jazz Series unfortunately contradicts itself between the documentary film and a published book version with two different sales figures. The facts are that Enrico Caruso, an Italian opera tenor, was the most popular recorded  musician up to the ODJB recording in 1917. Enrico Caruso was known as the first million seller and in order for the ODJB to become more popular and outsell Mr. Caruso they had to sell more than a million copies.
