Digital cameras are pushing film to the dustheap, but as long ago as 1949, cameras designed for the trash can had already been developed, when Photo-Pac marketed a $1.29 cardboard disposable that took 8 exposures. It was Fujifilm's Quick Snap line of disposable cameras that gave the industry legs in 1986. Disposable 35-mm cameras still do a brisk business, even in the digital era. Don't believe it? Go to a wedding reception and look next to the centerpiece when you sit down.
