I tried to plot the AMR (average minute ratings) for the first 3 games for each of the last 5 seasons of the PBA. In the previous 4 years, the Opening Game was on a Sunday and the next 2 games were on a Wednesday. Only this year did the season start on a Saturday with the next two games on the Sunday.
This is an encouraging start for this season as more people watched the first 3 games compared to the previous 4 opening games. This is especially promising considering that Barangay Ginebra and Purefoods, the two most popular teams haven't played yet.
We will have to see if the good start in viewership can be sustained.
