periods in the prior year, primarily due to an increase in the number of regular season games, as well as contractual rate increases. Retail and licensing revenue increased $2.0 million and $2.5 million during the three and six months ended June 30, 2023, respectively, as compared to the corresponding periods in the prior year, due to increased attendance at regular season games and demand for City Connect apparel, partially offset by a reduction in demand for World Series Champions apparel. Other revenue, a component of baseball revenue, decreased $6.0 million during the three months ended June 30, 2023, as compared to corresponding period in the prior year, primarily due to fewer concerts at the stadium. Other revenue was relatively flat during the six months ended June 30, 2023, as compared to the corresponding period in the prior year, primarily due to a $3.9 million increase in spring training related revenue (ticket sales, concession revenue and other gameday related revenue), driven by a six game increase in spring training home games, and revenue from additional special events at Truist Park, offset by the impact of fewer concerts at Truist Park. The Braves have a long term local television broadcasting agreement with Sportsouth Network II, LLC. Diamond Sports Group, the parent company of Sportsouth Network II, LLC, is in financial distress and has filed for chapter 11 protection. While the pending bankruptcy proceeding of Diamond Sports Group has not previously had a material unfavorable impact on the Company’s revenue and the Company continues to receive scheduled payments from Diamond Sports Group, we cannot currently predict whether such bankruptcy proceeding is reasonably likely to have a material unfavorable impact on our revenue in the future.
