The original software disk version of
Carry-a-Tune was released in 2003. In 2004, the trademark “Carry-a-Tune” was replaced with “SingingCoach” in an effort to clarify the software’s specific function as the software was gaining publicity and notoriety by various publications such as
PC magazine. SingingCoach was sold in software brick and mortar giants, Best Buy,
Comp USA, and Target. In 2012, Franzblau opened his software up to exclusively e-commerce shoppers by offering a
downloadable version of SingingCoach, allowing customers to download the program directly from the website as opposed to picking up the software in a brick and mortar store. ==Pitch recognition technology==
