I haven't followed the poker scene in a while but back in my day (say 10 yrs ago) every casino, tournament, televised cash game etc. used the narrow/bridge size cards. I've noticed most of the recent clips I've seen have switched to using the wide size. Granted, that is the definition of "poker sized" cards and the game is "poker" but, when did this start becoming commonplace? And also, why? Card manufacturer decision, some high profile player(s) starting a trend somewhere along the line, etc?
Ironic how I threw away most of my wide cards to fit in with the crowd back then, and now that I want to take up poker again, I've got to start all over...
