> the wireless headset was the killer app in its early days

Don't forget music piracy.

At least over here, a lot of kids had phones that did Bluetooth, and the primary use case for it was sharing songs they liked with each other. You could use infrared (IRDA) for that, and some people did before Bluetooth was common, but it was much slower.

This was mostly on low-end Nokias, maybe with a bit of Sony Ericsson thrown into the mix. They definitely did not have WiFi, in fact, Nokia even tried to limit internet over Bluetooth for usual carrier monopoly reasons as far as I'm aware, but Bluetooth was definitely there.

For many here, the iPhone not doing file and ringtone sharing over Bluetooth was one of its main limitations, at least early on. It was a social network in its own way, and having a device that couldn't participate in it was no fun.

By "early days", I was more thinking about the 1999-2005 era, before low-end Nokias even got Bluetooth and the ability to play MP3s.

The wireless headset was the killer app that drove bluetooth adoption within cellphones, driving down costs until eventually the lower-end models receiving it too. While sharing files was possible in the 1999-2005 era (especially with PDAs), most phones were lacking enough flash storage to store anything worthwhile.

While I don't want to say file sharing wasn't a killer app, it does seem to have been limited to just schools during a certain time period.

A time period that I missed out on by a few years. At high school, we did all our file sharing by swapping burned CDs. Then we switched to dragging around laptops and USB hard drives at university (and using the private emule network on the university wired ethernet).

It may be worth articulating the Bluetooth headset specifically as the one-ear little clip headset executives and IT staff seemed to use to answer calls.

Remember companies like jawbone?

I vaguely remember a cultural stereotype of bmw drivers driving aggressively and wearing Bluetooth headsets. [edit: this is the clip https://youtu.be/UqfAMvXpSw4?t=25 from top gear of jeremy clarkson wearing a bluetooth headset in sunglasses in a bmw, supposedly from topgear season 10, episode 10]

Yes... there is a very interesting generational thing going on here.

Bluetooth headsets were very popular among a certain market segment (business people who made a lot of phone calls), but saw very little adoption outside of that. At that time, you often had to buy an expensive business grade phone to get bluetooth functionality.

Then once Bluetooth was common in cheaper phones, we see a completely different market segment (students at schools) rapidly adopting bluetooth for a completely different usecase (file sharing). It's hard to find two market segments that are more isolated from each other.

I don't think file sharing could have ever driven bluetooth to mass adoption on its own, partly because companies always overlook what school students are doing with technology. But mostly because the file sharing usecase required mass deployment of the technology before it could take off.

When I was in high school, I had a palm PDA with IrDA that could do file sharing. But did I ever use it for file sharing? No, because nobody else had devices with IrDA. IrDA never hit the market saturation it needed to be actually useful, so there never was much demand for it (despite the hardware being really cheap, especially compared to a dedicated bluetooth radio)

Bluetooth headsets worked as a killer app in those early days, because a single BMW driver could buy both a high-end phone with bluetooth and a headset from the cellphone store and get the complete experience. It worked without market saturation.

Jabra! In all seriousness the blackberry Bluetooth earpiece was the killer app (hardware / device).

Worked perfectly paired with a bb.

Wow this unlocked a bunch of memories from middle school where we would send each other the latest songs and games via bluetooth. I remember pirating games for my sony ericsson and sharing them with my friends and we would play these games in class. You could just share and install the .jar files. Good times

What you describe is file sharing, not necessarily piracy :-). Just nitpicking, I understand what you mean of course!
