Hot Rod is the oldest magazine devoted to hot rodding having been published since 1948. Robert E. Petersen founded the magazine and his Petersen Publishing Company was the original publisher. The first editor of Hot Rod was Wally Parks who created the National Hot Rod Association. Petersen Publishing was sold to British publisher EMAP in 1998, who sold the former Petersen magazines to Primedia in 2001. Today it is published by Source Interlink, which purchased the magazine along with Primedia’s Consumer Magazine division in 2007.
