NASCAR is seeking a new title sponsor for its second-tier championship in 2015 after Nationwide decided to end its backing of the series in favor of programs in Sprint Cup.
The insurance company took over from Busch as the feeder series' title sponsor in 2008. Nationwide will retain a NASCAR involvement through new associate programs in the Cup series, as well as sponsoring the Betty Jane France Humanitarian Award.
Nationwide's chief marketing officer Matt Jauchius compared the move to a driver graduating to the premier championship.
"The NASCAR Nationwide Series is a great proving ground not only for drivers and crew members, but for sponsors too," said Jauchius. "It's a natural evolution for Nationwide Insurance to move our marketing investment to the NASCAR Sprint Cup Series and we'll continue to put tremendous effort behind all of our NASCAR marketing platforms in the years to come."
