Channel 7 has announced a deal with ARG to broadcast TCR, S5000, and other ARG categories free-to-air in 2020.
SBS has done a good job of introducing TCR, and without it I, for one, would not know TCR existed, and their coverage has been more than adequate IMO, but there has been criticism from those who probably expect the high level of broadcast that costs lots of money. However, Seven should bring us that high level of coverage, so all is good.
Obviously, the ARG group have big goals, and investing a large amount of cash into the sport generally, which hopefully broadens the audience without becoming so commercial as to turn fans away.
Bring on 2020.
