Yes... you may know of The Wall, a BBC3 show/website. The broadcast was originally meant to be hosted by Noel Fielding but he has backed out due to 'other commitments' (the Boosh tour, and writing the film, I guess... but still 'other commitments' always fills my heart with dread!) Now instead hosted by Rhys Thomas and Alexa Chung.

So what is The Wall. Well there is a site you can check out... but the short version is this...
You submit stuff (only photos, pics and vids... usual copyright, non-exclusive rights terms) It gets uploaded to the site (which exists but has no upload links at present... they will be adding relevant upload areas soon), and if its b**chin' hot comedy then it will be broadcast on tv on a show that will also contain bigger and smaller comedy names in sketches live and pre-recorded (so similar to Comedy Shuffle really... the only difference I can see really is that different names are attached to this).

Pro... you may get some of your material aired.
Con... this is another unpaid/unprized oppotunity which could well lead no-where!

So, if you just want to get your stuff out there (I am tempted, it has to be said) keep your eyes and ears open about this show/site.

Lily Allen's show on BBC3 also has a nice slot on for web videos, where they show about five a week... And they want submissions, too...

BBC3 is definitely a good platform, as the audience is certainly a similar bracket to those who are most likely to frequent the internet sites... So once your name was known there, they'd look for you online as well... Could be good...

what happened to Lilly Allen and friends show?
I heard the people who came to the show was really bored, and they have to stand for ours,
