Internet video is coming of age, with the best amateur film-makers attracting millions of online viewers.
Two of the web's hottest film-making teams have made videos for the BBC News website, talking about what they do and where they think it will lead.
Ian Hecox and Anthony Padilla are two 19-year-old college students from Carmichael, California.
They are also two of the biggest stars on YouTube, where they go under the name of Smosh.
They started by filming a spoof music video for the Pokemon theme tune, which is now YouTube's second-most watched clip of all time, with 17 million views.
They have since branched out into their own comedy sketches, which have established the pair as firm favourites among the online video audience.
Blame Society Productions is the film-making enterprise of two friends from Madison, Wisconsin - Aaron Yonda and Matt Sloan.
They have been making short films together for four years and are currently enjoying huge popularity with their online series Chad Vader: Day Shift Manager.
It stars Darth Vader's younger and slightly less successful brother, who has found a career managing a grocery store.
They have a wide range of other comedy short films in their archive and hope the online attention will translate into mainstream TV success.
