Pokémon Go is unquestionably this season's hit game. But whether it has any staying power is a very open question, and early signs suggest it's already trailing off.
Bloomberg has published some charts by Axiom Capital Management that show daily users and engagement dropping. One chart, using data from analytics firm Apptopia, shows Pokémon Go peaking at around 45 million users in mid-July, during the week or so following its launch. It then begins a decline to somewhere above 30 million daily users last week.
