Yes, since SPEED has (?) dissolved, motorsports TV coverage has decreased, in my market at least.
The only thing that has not changed is F1 coverage. Indy may or may not have but I started watching 3 seasons ago so I don't know what it was like before then.
Even NASCAR coverage has dropped this year.
This has to be the first year I remember Cup qualifying that was tape delayed to the next day.

And I have been watching a long time, not that I watch every Q session.
No more WRC, V8 Supercar, BTCC or WTC over the last year, 2 for some, while just getting this season's WTC coverage for the 4th and 5th events (I think). Conti races last year where tape delayed but I think all of them where televised.
This year only 2 so far, skipping the next 2 (including my home town LRP) and then back to the Glen.
2 or 3 years ago we had Darrel Waltrip and Mike Joy covering Bathurst at the track, now notta.
I'm not saying SPEED was the ultimate reason that TV coverage has decreased (and it may very well be the reason) but since SPEED has (?) dissolved, TV coverage of motorsports racing has decreased.
Oh joy, I do have 1 hour television coverage for each of the Silverstone and Spa 6 hour races.
Even though it seemed I saw more of Belgium than actual race coverage for Spa.
Oh and "lights out" at 26 minutes into the coverage of Spa.

I would rather see the Conti coverage than WEC.
I prefer these classes (ST/GS) of cars and the racing involved more than any prototypes, be it DP or LMP. Same as the GT classes world wide, it's great racing.
I realize that not all think the same as I but what about those who do?
I do not want to pay more for a premium race channel as I did with SPEED, I pay enough already.
On another note, Lime Rock was wet for qualifying and qualifying was cancelled. Teams spent the time practicing in the wet.

The GT3 Cup Porches were doing wheelies over the hill.

Even greater than the Pirelli World Challenge cars last year.
That must be some feeling the first time a driver lifts the wheels, and for that long, wow!!
