The Lynx was more popular in UK than US. Most video game shops in my area (Software Cavern, Computer Care South, Ultima Computer Shop) had Lynx games, Lynx was well featured in UKs gaming magazines, for example C&VG, Mean Machines, etc. Of course, me and Colin always wrote about Atari Lynx in our fanzine 8/16, and also Edwin and I did Lynx User/Atari Entertainment.
Telegames always advertised in most UK gaming magazines for the Lynx. In London was Silica Shop and CEX. I think all this helped a bit.
Mind you, in UK most of the girls wanted Game Boys
