The Podcasts app is just the latest product to go through a process I’ve come to call The Google Cycle. It always goes the same way: the company launches a new service with grandiose language about how this fits its mission of organizing and making accessible the world’s information, quickly updates it with a couple of neat features, immediately seems to forget it exists, eventually launches a competitor out of some other part of the company, obviously begins to deprecate it and shift focus to the new competitor, and then, years later, finally shuts it down for real. The Google Graveyard is full of apps like Reader, Duo, Inbox, Allo, Wallet, and countless others that have been through The Google Cycle, and it feels just as bad every time.
My understanding is that this is because of the way they operate internally. They reward new initiatives but not maintaining old initiatives, so employees are heavily incentivized to sunset old apps in favor of new apps that are functional replacements, and this cycle is the result.
