Known as "The Computer Flight People", subLOGIC (Sublogic Communications Corporation) was a small game company based in Champaign, Illinois. They are best known for the development of Microsoft's original Flight Simulator series in the 1980s, as well as their own flight simulators such as Jet in the late 1980s and early 1990s.
subLOGIC was bought by Sierra in 1995. The subLOGIC name is no longer used; related products are released under the Dynamix label also owned by Sierra.
subLOGIC released a biannual newsletter called "Computer Flight Newsbriefs". Each issue was 4-6 pages long, and contained info on new/upcoming products, marketing strategy, and a list of products available for direct order.
