BBC World and BBC News 24 ran an interview with a bogus Dow Chemical official who claimed the company admitted responsibility for the Bhopal disaster in 1984. He also claimed the company had established a $12 billion fund to compensate victims' families and survivors of the disaster.
The BBC has apologised to Dow and to viewers who may have been misled.
I have a paper copy of this print ad from 1962 about how Union Carbide was "Building a New India", apparently by having a giant, disembodied hand dump blood onto the fields.
