june utc then maybe it would be useful to mention this in the history section making a reference to the name of the company that was being used during the time when the events discussed happened for example if the paragraph is talking about events between and then it should refer to the company as british petroleum if the paragraph is talking about events between to then it should be referred as bp amoco the point i'm trying to make is that the words british petroleum appear only once in the entire article and are not representative of the amount of time the company carried that name
