(written from a Production point of view)
Polar Lights Models was the model-making division of the toy company Playing Mantis, set up in 1994 with the specific intention to re-issue Aurora Plastics Corporation's signature monster and science fiction kits of the 1960s and 1970s. The company's name itself was an homage to "Aurora" (both references to the northern and southern polar lights). Apart from the figurine kits, the company also produced scale models of famous vehicles from various TV and movie projects, such as the Ghostbusters ECTO-1 and the Back To The Future Delorean Time Machine.
In 2003, Polar Lights started to release Star Trek model kits, including some not previously released designs, having been given the license as then owner of AMT/Ertl (hitherto the regular licensed manufacturer of Star Trek model kits), Racing Champions, showed no interest to develop the Star Trek line any further. At that time, no Star Trek model kits had been marketed for four years. Unfortunately, Playing Mantis itself was acquired late 2004 by the same Racing Champions and production of new model kits was halted immediately by the new owner, which resulted in 2006 in the announcement of Polar Lights' closure, due to the elimination of the brand. 
Yet, a year later, the product line of Polar Lights was sold to Round 2 LLC, which also acquired AMT the same year, and the brand was revived in 2008, resulting in that all US-based licensed Star Trek model kit manufacturers were once again under one roof. In June 2009, Round 2 indicated that they would start releasing entirely new models under the Polar Lights brand, including the Enterprise from Star Trek (slated for 2010 release, postponed to 2011, and finally canceled in 2012), in addition to other kits, by 2010.
