SKUSA SuperNationals XVIII to be Televised Primetime on CBS Sports Network via Torque.tv
Wednesday, 05 November 2014 17:01

Superkarts! USA has today announced that the upcoming SKUSA SuperNationals XVIII will be televised on major primetime network television via CBS Sports Network. The move comes as a result of a new partnership with motorsports specific upstart, Torque.tv

Torque.tv is the new production venture from Roger Werner, the visionary who founded Speedvision (and later SPEED Channel). The network will serve as a motorsports specific destination for racing and automotive enthusiasts worldwide. The network’s business model will combine both a revolutionary on demand subscription package with traditional primetime network television broadcasts. Both mediums will combine to provide an all-inclusive destination for viewers on a myriad of devices, including TV, mobile, and tablet.

The deal is one of great pride for SKUSA CEO Tom Kutscher. “We’ve been approached many, many times about putting karting on TV. It’s something I’ve been very eager to do, but I’ve been adamant it be the right fit. With the sport in a very pivotal growth stage, it was important to me that the end product show karting in the appropriate light. I am very pleased to say we’ve finally found the right match in Torque.tv and the CBS Sports Network.”

“For 10 years now, MG Tires has been a big supporter of the ProKart Challenge and Superkarts! USA.
