My first exposure to "feeding" was Diablo 4 Gold through Fate/Grand Order, which was originally out on Japan in July of 2015. It grossed a total of $4 billion dollars across the globe in 2019. To make a character as good as possible, I needed to obtain duplicates of each.
When a particular advertisement came up I spent more than 300 euros to purchase the five-star character I'd coveted since a long time. However, I wasn't able to get the copies I needed for the full potential of the character.
With the rates for the most sought-after 5-star characters being around one percent, it's an unsurprising that I did not manage to get a copy of the character during gaming (which I've since deleted).
As of July 20, 2021, Fate/Grand Order was the seventh most popular mobile game to be sold all time. It was placed in front of Konami's Puzzle & Dragons, which could be added to the list because it is also a gacha-based game.
During an GDC 2021 talk, Genshin Impact developer Hoyoverse (previously Mihoyo) outright admitted that its method for designing characters was focused on generating most money possible from its fans. The Raiden Shogun as well as Kokomi character reruns from March 2022 alone netted the company over $33 million in revenue.
The event became immortalized in jokes and memes, a lot of which stemmed from disappointing expectations of the public: Fans attending BlizzCon 2018 were anticipating "Diablo 4" news. However, it was also a result of a lingering stigma around smartphones and games played in the West as the acceptance of smartphones as cheap Diablo IV Gold a gaming platform has been slower than the rest part of the globe.
