The new contracts increase the amount of coverage from each weekend's races. All practices for NEXTEL Cup Series races are now televised, whereas only the final practice ("happy hour") was carried before.

In addition, all Busch Series final practices and qualifying sessions are now shown; before, a few qualifying sessions were not seen and only a handful of practices were seen. Most, if not all, truck series time trials will also be broadcast.

Other changes include revamped graphics and expanded telemetry. Also, Fox has unveiled "Fox 3D," which will replay various moments as it looks from virtual reality.

The advent of the internet has opened the door for many new ways to publish information. Even though NASCAR tv ratings are going through the roof, NASCAR related web sites, podcasts, and video casts, are proliferating at record speeds.

Luckily for those who don't havea television today, they can still listen to NASCAR of the Internet with MRN radio.

The Motor Racing Network (MRN) is the radio broadcasting operation of NASCAR. It broadcasts coverage of most major NASCAR races at the top three levels of NASCAR: the NEXTEL Cup, the Busch Series and the Craftsman Truck Series.

The exception to these are races held at tracks controlled by Speedway Motorsports, Inc., which operates their own radio network called the Performance Racing Network, and the Allstate 400 at the Brickyard, which is broadcast by Indianapolis Motor Speedway's own radio network.

All Craftsman Truck races are broadcast on MRN regardless of track ownership. The Nextel Open and Nextel All-Star Challenge are also broadcast on MRN despite being held at Lowe's Motor Speedway, an SMI-owned track. MRN promotes itself as the "voice of NASCAR".
