We can often see this media view: Bitcoin uses blockchain as the underlying technology. Seeing this sentence, for the vast majority of ordinary people, they will definitely confuse the relationship between Bitcoin and the blockchain. They would think that blockchain technology was born first, and then Bitcoin was born. This is why many governments ban Bitcoin but not blockchain. They will advertise that blockchain is a very good and very advanced technology. But Bitcoin is a very risky asset and a bad thing.
The term "Blockchain, the techology" was mostly introduced to capitalize on the idea of Bitcoin without actually acknowledging Bitcoin. The reason for this is that Bitcoin by it's very nature can not be controlled by a single party, and that's something neither governments nor cooperations like. They don't want to use a platform, they want to be the platform. If cooperations could they'd force people on their own version of "Internet, the technology" and arguably they've largely succeeded.
But as ranochigo pointed out, blockchains, or rather blockchain-like structures have existed for quite a while before Bitcoin. Git, for example. But nobody would call a Git Repository a Blockchain because that'd be stupid. Or rather, because it's missing a critical component, that is, a decentralized and secure consensus algorithm such as Proof of Work. But most "Blockchain, the technology" projects seem to largely ignore the consensus part of the equation, hence why they fall a bit flat.
