In 2018, Haran released a spin-off audio podcast titled *The Numberphile Podcast*.^{[7]}

The *Numberphile* YouTube channel was started on September 15, 2011. Most videos consist of Haran interviewing an expert on a number, mathematical theorem, or other mathematical concept. The expert usually draws out their explanation on a large piece of brown paper and attempts to make the concepts understandable to the average, non-mathematician viewer. It is supported by the Mathematical Sciences Research Institute (MSRI) and Math for America.^{[8]}^{[9]} Haran also runs the "Numberphile2" channel, which includes extra footage and further detail than the main channel.^{[10]}

The channel was nominated for a Shorty Award in Education in 2016.^{[11]} *The New York Times* has said, "At Numberphile, mathematicians discourse, enthusiastically and winningly, on numbers".^{[12]}

The channel has featured mathematicians, computer scientists, scientists, and science writers, including:^{[13]}
