In 1965, Kunzel began the country's first winter pops series, the "8 O'Clock Pops". When the Cincinnati Symphony Orchestra board of trustees created the Cincinnati Pops Orchestra in 1977, Kunzel was named conductor. The Pops became the larger of Cincinnati's two orchestras, as all of Max Rudolf's symphony orchestra also played for the Pops year-round. At the invitation of Arthur Fiedler in 1970, Kunzel guest-conducted over 100 concerts with the Boston Pops Orchestra. He remained active with symphony, leading the Indianapolis Symphony Orchestra (as Principal Pops Conductor) from 1982 to 2002.
