Depending on the artist, it can be.
The only artist that would fit in the category "mainstream" is Skrillex.
But there are other artists like Burial or newer ones like Obsidia that don't fall in this category.
Other artists like Alex Clare, are very popular, but dont count as full Dubstep, since they just use some elements of it and combine it with other elements from other genres.
Yes it is one of the most mainstream music genres currently in the world.
Deadmau5 does not release dubstep music in the mainstream scene. He does not release it in his albums and EP's as he is a progressive house and electronic music artist. However, he does release some dubstep music on his Soundcloud page. Check the related links for link to his Soundcloud page.
Dusbtep became popular around 2010 thanks to mainstream musician "Skrillex". But, he did not create it. Dubstep is a sub-genre of "Dub" and "2-Step" which are sub-genre's of Electronic Music. Dubstep was first thought up by an unknown British musician who visited Jamaica in the late 80's and heard the heavy bass from the over-used speakers. He went home and purposly distorted his speakers and made heavy bass lines and it made "Dubstep". Over the years as technology got better and computers became better, Dubstep was still VERY underground. People like Skream made Dubstep and we're the first to make it somewhat mainstream in the UK. In early 2010 Skrillex released "Scary Monsters and Nice Sprites" which blew up around the globe and held the #1 iTunes song for 3 weeks straight. This made dubstep and other producers skyrocket. As other producers like Datsik, Excision, 12th Planet and many more used the door Skrillex opened to promote their own music making dubstep a world-wide sensation. As of today, Dubstep is no longer "cool" it is now a semi-mainstream genre consisting of listeners who have always listened and loved the genre.
