Once photocopying became relatively available and inexpensive, the method was rapidly adopted. Most photocopied fanzines looked very similar to each other, unlike the more handcrafted appearance of mimeographed zines. Mimeography was still less expensive than photocopying (unless the faned was able to get free copying at work), but photocopying was much easier.
Donn Brazier's Title was among the earliest photocopied fanzines. Bill Bowers was another early adopter, switching from the more costly offset printing he had been having professionally done for Outworlds.
