History Channel Tense

After watching the short clip on prohibition which I found on the History Channel's videos section, they did not use the historical present tense as they had done in the film on vikings. The narrator of the clip spoke in past tense and talked about the key figures and dates that OCCURRED, rather than what was occurring. I do notice that most of the historical programs on the History Channel (not Ax Men...) use the historical present tense, which I actually enjoy listening to because of the storytelling element to it. It creates a program that may be more geared to attracting viewers than being semantically accurate, but I think that that is what the viewer should expect of a television program. Any other channel is showing sex, drugs, or violence, so History Channel has to make some money.
