The 4-man bobsled has been around since the very first Winter Olympics in 1924, with the following two exceptions: In 1928 it was the 5-man bobsled. In 1960 the event was not held because the organizers didn't want to build a bobsled track.
Bobsled is an Olympic sport where either 2 or 4 men/women get into a small aerodynamic sled and go down and ice track. It is very popular in places that have a large amount of snow during the winter or year around. Images and technicals of a bobsled can be viewed in the link below.

Technically speaking there are no Bobsled World or Olympic Records. The reason being that every track is different, no two courses are the same so you can't have a single record. However, since each track is different, they all have their own Track Records in both 50m start time and finish time. These track records could be considered World Records since it's the fastest time anyone in the world has ever posted that time on that track, but it's not an official World Record. As for Olympic Records, the Olympic Winter Games would have to be contested on the same track more than once which is not a very common situation.
