Look at the popularity of BTCC since ITV have aired the action live on a Sunday.
For me, gradually losing interest. Yes, I can pay for F1 on Sky. I don't need all the other channels as I don't watch TV that much. I might revise my opinion, otherwise, my interest will definitely dwindle further. Its a shame as I like Channel 4 coverage. The C4 F1 highlights show, given the restrictions imposed in 2019 is a shadow of its former self.
I have ended up watching US racing or classic F1 on YouTube which are popping up. Nascar have the full 3 hour race in HD on YouTube. The adverts are removed and the sound mutes whenever adverts aired. Usually released the day after the race. Obviously Sky or F1 will never do this and you will have to pay!
