I've mentioned many times these TV ratings, but now I found this nice table and graph. Thanks to Cicloweb forum.
Above, in the colored column, you can see the peak audience (in thousands viewers) for each stage, in all the RAI channels combined (Italy only). The column on the far right shows the corresponding share, which is more meaningful imho.
Here we have a graph of the share.
The stage share is the pink line, the others represents all the Giro-related RAI shows.
Here some other calculations:
Average share for officially flat stages: 11.8 %
Average share for medium mountain stages: 15.3 %
Average share for high mountain stages: 25.3 %
Average share for time trials stages: 11.7 %
I think these data explains quite a lot of the philosophy behind the Giro routes of recent years. Italians don't like TTs. AND flat stages, too.
It's really meaningful the audience of the final stage, despite being decisive for the GC. Not to mention the TTT.
EDIT: One last thing. I want you to note that this data, both in share and in absolute numbers, are really good and match the ones of all past Giros.
