[3] Starting in 1969–1970, having tried unsuccessfully to market the programs, Pimsleur gave them to Charles A.S. and Beverly Heinle at The Center for Curriculum Development in Philadelphia.
In 1983, Charles Heinle introduced SyberVision Systems founder Steven DeVore to the Pimsleur Russian program.
In 1995, Simon & Schuster took on distribution of Pimsleur courses to bookstores while SyberVision continued marketing them through other channels.
The courses continue to be produced in Concord, Massachusetts, and are available as digital downloads, CDs, and in interactive software formats for select languages.
In 2008, Pimsleur's first children's line, Speak Spanish with Dora & Diego, was released in coordination with Nickelodeon's Nick Jr.
In 2010, Pimsleur donated its Haitian Creole course for free to relief and charity workers after the devastating earthquake in Haiti.
[4] In 2010, Pimsleur partnered with the USO, The Boston Foundation and Playaway to produce Pashto and Dari courses for U.S. troops serving in and being deployed to Afghanistan.
In 2011, Pimsleur donated eight hours of its Japanese course to support aid agencies and volunteers in the wake of the tsunami disaster.
[9] In 2013, Pimsleur donated 15 lessons of its Tagalog course to support aid agencies and volunteers in the wake of Typhoon Haiyan.
[10] In 2015, Pimsleur released three additional Unlimited languages (Mandarin, Portuguese, and Russian) in its interactive software format.
In the same year, Pimsleur started selling its courses via a subscription model on its website for the UK, the US, Canada and Australia.
Pimsleur courses are audio based with supplemental reading and study materials that accompany the recordings.
The most comprehensively developed Pimsleur Language Programs (those with three or more levels) cover a wide range of material relevant to learners traveling or living in a place where the target language is spoken: Learners who complete a course with 3-5 levels should expect to be presented with 1500-2500 vocabulary words.
