Definitely 126 did much good for snapshot photography....I remember many friends in my student days, who wouldn't have otherwise taken photos, using 126 cameras (and flashcubes) regularly. IIRC, 110 wasn't quite as popular....the quality of processing could be variable, and most casual users kept with their 126 cameras. or graduated to the easier-loading 35mm which became available. There was also the Agfa Rapid easy-loading system, which never really took off, at least in the UK. (Agfa also produced 126 cameras and film).
