The fact that it's video first was necessary but not sufficient

yes thanks, that is much more clear

vine did

snapchat isn't the same

they both had implementation differences and primarily execution differences that had little to do with their platform, and more so finances

its not just video, its video+algorithm, its video+algorithm+content-subsidies

a lot of popular content creators on TikTok are still from the vine days, getting paid a lot more directly by the platforms now, as well as from whatever they can monetize on and off the platform.

Bytedance (TikTok) is willing to throw a lot of money at this, and they've been extremely high on compensation for engineers for years before TikTok reached critical mass.

snap is not video first — yes it supports video, but it supports pictures just as well or better since they integrate into chats.

vine was literally killed by twitter.

vine did! twitter mothballed it.

Twitter mothballed it’s because it didn’t catch on like TikTok did.

Vine was forced to intergrade into Twitter.
