Ken Burns and Lynn Novick’s documentary The Vietnam War averaged 6.7 million viewers across its 10 nights in Live+7 stats, PBS said today. The epic docu enjoyed a reach of just under 34 million.

These ratings results mean The Vietnam War is the second-highest-rated Burns/Novick film of the past two decades, following The War in 2007, PBS boasted.

Burns’ best-known documentary for PBS, The Civil War, aired nearly three decades ago. Looking back across two decades also excludes some other well-known Burns/Novick docus for public broadcasting from the conversation.
