- We explore the how much sport-events affect the - engagement + We investigated how specific sports events contribute to + engagement on YouTube using Difference-in-Differences + (DID). The analysis focused on data from 2017-2018, a + period when YouTube was becoming more mature. We + examined how the delta_view (change in views) of videos + in the period before and after sports events changed for + five sports: football, skiing, basketball, hockey, and + rugby. The corresponding events were: FIFA 2018, Winter + Olympics 2018, NBA Finals 2018, Stanley Cup Finals 2018, + and Rugby World Cup Sevens 2018. The control group was + the average delta_view of videos from sports unrelated + to the events, and the sport group was the average + delta_view of videos related to the event in question. +
++ The key finding is that not all sports events contribute + to increased engagement in their respective sports. +
++ Football and Skiing: + These two sports show the most significant impact from + their events, as the graphs clearly demonstrate. + However, when examining the p-values, football shows all + p-values below 0.05, indicating a strong, positive + impact from the FIFA 2018 event, with statistically + significant coefficients for both the treatment and + interaction terms. On the other hand, skiing shows a + weaker and less consistent pattern, with the Winter + Olympics having little effect on engagement and no + significant interaction term. It's important to note + that for this DID analysis, we examined the data for 4 + months before and 4 months after the events. Therefore, + we can conclude that user engagement for skiing did not + sustain for long after the Winter Olympics. +
++ Basketball, Hockey, and Rugby: + For these sports, the events did not show a substantial + increase in engagement. Particularly surprising was the + lack of change in engagement after the NBA Finals. + Despite the large number of basketball-related videos, + there was no noticeable shift in engagement. This could + be due to the NBA Finals being a U.S.-centric event, not + a global competition, and since it is a culmination of + the season, engagement may not increase significantly + afterward. For hockey, the post-event engagement + actually decreased, which is puzzling. This could be + because the Stanley Cup Finals took place in June, a + time when interest in winter sports, like hockey, + typically wanes, suggesting that the timing of the event + is critical in sustaining user interest. +
++ From these findings, it is clear that sports events do + not always affect engagement on YouTube. However, for + sports like football and skiing, the effect was + noticeable. Additionally, it can be concluded that for + minor-sports to capture more attention, the event needs + to be held on a global scale and during an appropriate + season for the sport.
