Again a late ratings piece because there really is not a lot of ratings up on BARB. At first I did not see much point in publishing this post, but thought I should for completeness purposes.
Starting with ESPN, live coverage of the IndyCar Series from Sonoma averaged 8,000 viewers. Other than that, the only thing worth noting is highlights of the Silverstone Classic which brought 26,000 viewers to ITV4 +1.
Motors TV’s highest rated was 27,000 viewers for Hotrax Motorsport. Whatever that might be.
