Well, the WRC tv coverage is pretty mediocre. How the production company can manage to make something so exciting (somewhat road based cars flying over jumps at 200km/h) boring is a testament to the fact that the media needs to be changed.

Also, while the other events and series you've mentioned are indeed popular, WRC still has a massive following worldwide and should be able to get support.

The last two seasons have been more exciting and entertaining for me than anything else in the past decade. I have high hopes for the 2017 season, hopefully redbull gives the media a good step up!
