What is the meaning? 'They created a buzz that has taken on a life of its own'

[Maxspeed]

I have cited this sentence from a passage about the new iphone.

Many thanks

Hi,

I think the complete sentence should read: They created a buzz that has taken on a life of its own.

This could mean: they have created an excitement that has increased and is now a considerable force in itself.
