Got a reply from BBC
Thank you for your e-mail. The BBC only has limited resources and has to
spread those resources across a great number of sports, including many
minority sports which other commercial broadcasters do not cover. Along
with the major sports, we make a priority of covering those to which we
have broadcast rights, and Olympic sports. This does mean that sports
such as downhill mountain-biking are likely to miss out.
We do on occasion cover world titles in sport that fall out of the
parameters set out above but it’s a case of when staffing allows.
Unfortunately the downhill mountain biking fell on a massive weekend of
sport – with Olympic sport including athletics, rowing, basketball – and
we weren’t made aware of the event beforehand or the results afterwards
by the body in charge of the event.
In addition, we’ll be getting in contact with our regional journalists
to investigate the possibility of doing a piece with Danny Hart.
Kind regards,
BBC Sport Interactive
The bit in bold I found interesting…
