John Adams bringing back the historical miniseries?

A poster on Associated Content wrote an article on how he thinks John Adams just might usher in a new wave of popularity for the historical miniseries in this article: http://www.associatedcontent.com/article/1055656/the_success_of_john_adams_prompts_a.html?page=3&cat=47
The poster seems to think that John Adams wasn't as successful on HBO as it could have been on more major networks. Does anyone else think that there is still a mainstream audience for historical TV? I don't think television is the best medium for historically accurate work. Although HBO may be able to stay true to its source, major networks have to worry about pleasing advertisers and drawing more viewers to increase ratings, which often comes at a cost to the accuracy of the source material.
