The case was dismissed because the cover art had not been registered as a trademark by the group prior to Berkeley Systems' release of the screensaver. The second case was brought in 1994 by 1960s rock group Jefferson Airplane who claimed that the toasters were a copy of the winged toasters featured on the cover of their 1973 album Thirty Seconds Over Winterland. District judge ruled that Delrina's 'Death Toasters' was infringing, Delrina later changed the wings of the toasters to propellers. The toasters were the subject of two lawsuits, the first in 1993, Berkeley Systems vs Delrina Corporation, over a module of Delrina's Opus 'N Bill screensaver in which Opus the penguin shoots down the toasters. The Flying Toasters were one of the key reasons that After Dark became popular, and Berkeley began to produce other merchandising products such as T-shirts, with the Flying Toaster image and slogans such as 'The 51st Flying Toaster Squadron: On a mission to save your screen!' Yet another version called Flying Toasters! added bagels and pastries, baby toasters, and more elaborate toaster animation.

A slider in the Flying Toasters module enabled users to adjust the toast's darkness and an updated Flying Toasters Pro module added a choice of music- Richard Wagner's Ride of the Valkyries or a flying toaster anthem with optional karaoke lyrics. Engineer Jack Eastman came up with the display after seeing a toaster in the kitchen during a late night programming session and imagining the addition of wings. The most famous of the included screensaver modules is the iconic Flying Toasters, which featured 1940s-style chrome toasters sporting bird-like wings, flying across the screen with pieces of toast.
