Monster Jam is a live motorsport event tour and television show operated by Feld Entertainment. The series is sanctioned under the umbrella of the United States Hot Rod Association (USHRA) and takes place primarily in the United States. Although individual event formats can vary greatly based on the "intermission" entertainment, the main attraction is always the racing and freestyle competitions by monster trucks.
Although Monster Jam events are held year round, the traditional competitive season (when televised shows are taped) runs from January to March, with a few events to start off the season in November. During the winter run, it is not unusual for up to 10 events to be run in different areas on the same weekend, with one or two major stadium events with 10-16 trucks, and a group of smaller arena events with 4-8 trucks. The season culminates in the Monster Jam World Finals in Las Vegas in late March. There is also a Monster Jam Europe tour in the summer and autumn, as well as a domestic series of summer events known as Monster Jam Summer Heat.
