The term "Dubstep" in reference to a genre of music began to be used by around 2002, by which time stylistic trends used in creating these remixes started to become more noticeable and distinct from 2-step and grime.
Interest in dubstep grew significantly after BBC Radio 1 DJ Mary Anne Hobbs started championing the genre, beginning with a show devoted to it in January 2006.

In 2004, Richard James' label, Rephlex, released two compilations that included dubstep tracks - the Grime and Grime 2.
These compilations helped to raise awareness of dubstep at a time when the grime sound was drawing more attention, and Digital Mystikz and Loefah's presence on the second release contributed to the success of their DMZ club night.
The Independent on Sunday commented on "a whole new sound", at a time when both genres were becoming popular, stating that "Grime" and "Dubstep" were two names for the same style, which was also known as "Sublow", "8-bar" and "Eskibeat".

Mary Anne Hobbs commented that the mood at dubstep nights is less aggressive, or more meditative, leading to a larger female attendance at events than with the genre's precursors, noting "Grime and drum 'n' bass raves tend to be quite aggy. People in dubstep clubs tend to have a more meditative approach, which is inviting to females. You see the female-to-male ratio constantly going up - it's got the potential to be 40:60".
Journalists Melissa Bradshaw, Emma Warren, and dubstep documentarian and photographer Georgina Cook have all had an impact on the cultural importance of the music.
The influence of dubstep on more commercial or popular genres can be identified as far back as 2007, with artists such as Britney Spears using dubstep sounds; critics observed a dubstep influence in the song "Freakshow", from the 2007 album Blackout, which Tom Ewing described as "Built around the 'wobbler' effect that's a genre standby." Benga and Coki's single "Night" still continued to be a popular track on the UK dance chart more than a year after its release in late 2007, still ranking in the top five at the start of April 2008 on Pete Tong's BBC Radio 1 dance chart list.
A key factor in the rise of dubstep in the media was its exposure on video sharing websites, such as YouTube who provide access to many channels dedicated to dubstep, notably UKF Dubstep.
In a move foreshadowed by endorsements of the sound from R&B, hip-hop and recently, mainstream figures such as Rihanna, or Public Enemy's Hank Shocklee, Snoop Dogg collaborated with dubstep producers Chase & Status, providing a vocal for their 'underground anthem' "Eastern Jam".

Post-dubstep More recently the term post-dubstep has been used to describe music that combines stylistic features of dubstep with other musical influences.
In September 2011 a Spin Magazine EDM special referred to brostep as a "Lurching and aggressive" variant of dubstep that has proved commercially successful in the United States.
Unlike traditional dubstep production styles, that emphasize sub-bass content, brostep accentuates the middle register and features "Robotic fluctuations and metal-esque aggression." According to Simon Reynolds, as dubstep gained larger audiences and moved from smaller club based venues to larger outdoor events, sub-sonic content was gradually replaced by distorted bass riffs that function roughly in the same register as the electric guitar in heavy metal.
The term brostep has been used by some as a perjorative descriptor for popular Americanised Dubstep.
Dubstep purists have leveled criticisms at brostep because of its preoccupation with "Hard" and aggressive sounding timbres.
