Okay - finally we have the complex viewing figures from Poland. I posted before only SF2 and Grand Final, there is a summury:
Semi-Final I - 1 964 822 (14,46%)
Semi-Final II - 3 842 057 (29,10%)
Final - 5 092 451 (41,66%)
Peak of the final - 6.320.000 (42,72%) - Michał Szpak's perforormance
This is number of viewers from two channels - TVP1 and TVP Polonia, both of them aired ESC live.
There is a table with viewing figures for previous editions but only on TVP1 (without TVP Polonia):
+ in 2004 - 6.677.000 (51,8%)
+ in 2003 - 8.369.000 (65%)
So, this is the best year since 2004.
