The very light jet (VLJ) is a classification initiated by the release of the Eclipse 500,[19][20][21] on 31 December 2006, which was originally available at around US$1.5 million, cheaper than existing business jets and comparable with turboprop airplanes. It accompanied a bubble for air taxi services, exemplified by DayJet which ceased operations on September 2008, Eclipse Aviation failed to sustain its business model and filed for bankruptcy in February 2009.

Though the early Lockheed Jetstar had four, most production business jets have two jet engines, mostly rear-mounted podded engine. If mounted below their low wing, it wouldn't allow sufficient engine clearance without a too long landing gear. The HondaJet is the exception with its over the wing engine pods. Dassault Falcon still builds three-engine models derived from the Falcon 50, and the very light jet market has seen several single-engine design concepts and the introduction of the Cirrus Vision SF50 in 2016.
