-						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.
+					</p>
+					<p>
+						The key finding is that not all sports events contribute
+						to increased engagement in their respective sports.
+					</p>
+					<p>
+						<strong>Football and Skiing:</strong>
+						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&#39;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.
+					</p>
+					<p>
+						<strong>Basketball, Hockey, and Rugby:</strong>
+						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.
+					</p>
+					<p>
+						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.
