Pomplamoose's primary platform is YouTube. All of their songs come with videos of varying complexity that they post there on a regular basis. They started doing this in 2008 when there weren't many "creators" on the platform posting quality material consistently - it was before the era of the "YouTube star."
Their methodical approach gradually built them a huge fanbase that connected with them on an intimate level, quite a contrast to the YouTube sensations that had a viral video but were soon forgotten (we're talking to you, "Chocolate Rain
" guy). By the time other performers realized YouTube could build a career, it was saturated, but Pomplamoose was already out to a commanding lead with enough subscribers to sustain them as long as they kept making music.
