There's not much evidence to suggest any long-term attendance trends are linked to start times. Game length? Maybe, although attendance was fairly steady through the 2000s and 2010s as the average game length went up. Overall, attendance since 1998 hasn't changed all too much (70.6 M in 1998; 71.3M in 2024). Attendance did drop off from 72.6M in 2017 to 68.5 in 2019, and 2023 it was back to 70.7 This is not to say the pitch clock and faster games aren't good (they are) but it's much harder to say the start times matter much. Separately, and since I was curious, teams that use 7:05/7:10/7:15 start times on weekdays: Teams with year-round 7:05/7:07/7:10/7:15 (local) weekday start times: Atlanta, Los Angeles, Houston, New York (both), Sacramento, Tampa, Texas, Toronto A bunch of teams (Baltimore, Detroit, Miami, Milwaukee, Kansas City, San Francisco, Seattle) have post-7 start times on Fridays, and earlier Mon-Thu. Boston, Cincinnati, and the Cubs do post-7 start times in the summer and earlier in April/May/September.
