It appears that now the NHRA have gone away from ESPN, broadcast rights in international markets may not have been considered. I know that the NHRA Mellow Yellow series is currently not scheduled to be broadcast in Australia (previously Foxtel) and I have also heard that its currently not going to be broadcast in the UK.
If you enjoyed watching American drag racing via your pay TV supplier, double check that you still can! If you can’t make sure you lobby your Pay TV Supplier, the NHRA and even possibly the teams.
For those in Australia, there has been a facebook page setup https://www.facebook.com/groups/1683587361890156/ . Over the last 2 days over 3000 people have joined the page. Foxtel are also answering questions via their facebook page and appear to be looking into it.
