The channel's purpose is to give Smosh's Spanish speaking audience the ability to watch videos in their own language. The channel was used at first to only dub main Smosh channel videos dubbed into Spanish. For the first five months, two Spanish translators named Juan and Antonio dubbed the videos with Juan as Ian and Antonio as Anthony.
On July 1, 2012, Ian and Anthony announced that Patrick NeluaM, the creator of the channel NeluaMNelu (now Patrick NeluaM), a fan channel that dubbed various YouTube videos including Smosh videos would become the translator, replacing Juan and Antonio. Ian and Anthony said that ever since starting ElSmosh, fans commented that Patrick would be better suited for dubbing than Juan and Antonio. He replaced them on July 8, 2012.
Along with dialogue, titles on the channel are also translated to Spanish.
