Santa Ana, CA ¿ September 9, 2005 ¿ Advanstar Communications, Inc. ¿ a leading provider of print, event and online media for the powersports, off-road and automotive aftermarket industries ¿ today announced that they have reached an agreement with MotocrossLive to produce the live internet broadcast for the 12-round BooKoo Arenacross Championship Series presented by K&N Filters.

The live broadcast for the BooKoo Arenacross Championship Series will begin 30 minutes prior to each event and include transponder feeds, rider interviews, interactive chat rooms, special interest stories, and real-time audio coverage of what¿s shaping up to be the most entertaining and competitive Arenacross series ever. Coverage will be archived after the series on the dirt bike section of off-road.com so die-hard fans can indulge their desire to reminisce.

“The demand for live coverage of motor sports events continues to rise dramatically, and Bob Davis and B.H. `Pat¿ Forbes, the talent behind MotocrossLive, have invested years developing technology to broadcast these events and bring them into the homes of millions of enthusiasts,” said Mike Kidd, Arenacross Race Director for Advanstar. “We looked at several proposals, and the one from Motocross Live was incredibly in-touch with our need to capture the hearts and minds of racers and fans, whether they¿re in their hometown Arena¿s seats or thousands of miles away in their own home,” added Kidd.

The MotocrossLive broadcast will be housed on the dirtbike section of www.off-road.com (at MX off-road) and the racearenacross.com website for easy access to the events, and sponsorship opportunities will be available against both real-time and archived coverage online. With over 700,000 unique monthly visitors to off-road.com and over 5 million impressions per month, sponsorship opportunities will abound and provide supporting manufacturers with an unprecedented reach to the Arenacross community nationwide.

“With MotocrossLive behind the controls of the broadcast, and the pre-eminent website for off-road enthusiasts in the driver¿s seat, we have no doubt that the BooKoo Arenacross Championship Series will raise the bar to a new level of exposure for racers, fans, and the sponsors who choose to support us,” said Skip Johnson, Vice President of Advanstar Communications. “Advanstar is the first to offer live Internet coverage of Arenacross racing, and that is the position we need to be in to reinvent this great sport,” continued Johnson.
