I'm surprised that the Biased BBC website has not been linked yet.
A few themes they have are:
blatant bias against the Republicans and in favour of the Democrats/Obama (very blatant and obvious, because it's not the UK so they can get away with it more)
bias against Israel
ignoring the nationality of foreign criminals, Islamic terrorists, etc., e.g.,
biased-bbc.com/2012/05/08/the-missing-words/
They point out that the BBC www.bbc.co.uk/news/uk-england-17989463 manage to make NO mention of either 'Pakistani' or 'Muslim' in the grooming rape story.

basically unnamed people were supporting terrorism by smuggling khat. The essential missing information was that this was Islamic terrorism, and that the people involved were Somalis, so the article was completely devoide of context. (by contrast the BBC will ALWAYS point out the background of BNP/EDL types)

"Hence we see the Algerian illegal immigrant transformed into a man from ?Shepherds Bush?, the Moroccan drug dealer (obsessed with beheadings and al-Quaeda videos) who becomes a man ?from Lisson Grove, north-west London? (with no notable habits), the Somali ?of Small Heath, Birmingham?, the Nigerian nationals and illegal immigrants who become ?South Londoners? "
"There?s one notable exception to this rule ? if the foreign national is American the BBC goes to town on the story. Even if he?s a naturalised British citizen he?ll always be American to BBC news."

Manages not to mention 'Muslim' in a story on FGM.
