You could add substance to your comment by listing some things that became big after 2010, and saying whether or not they seemed like toys early on.

One example: Bitcoin (2009, but few had heard of it before 2010), cryptocurrencies and blockchains. I think these support cdixon's claim.

Another: Snapchat (2011) and other ephemeral messaging apps. These certainly seemed like toys.

Beanie Babies looked like toys early on, too.

Just because something found a market doesn't mean it's not still a toy.
