Charles Band started Wizard Video in 1980, distributing a number of horror classics (and trash classics) as well as introducing the “big box” VHS format. The big boxes splashed graphic art and were a signal innovation that changed the market. You can see a whole bunch of awesome brochures here. Wizard Video also released two obscure, ultra-violent video games for the Atari 2600, Halloween (1983) and The Texas Chainsaw Massacre (1982).
