I just have bad memories of a pan-European press conference in Japan a couple of years back run by a company I won't name, but which rhymes with pony.
We all had to sign non-disclosure agreements (NDAs) before we were allowed to attend the product launch, agreeing not to publish anything before a set embargo date. No signature, no attendance at the launch.
Oh, and to make sure no-one did the naughty, there was to be no photography when we were shown the products.
So we all signed them, and trooped into the conference room, whereupon a group of French journalists said they weren't going to sign, as the date set meant they'd miss their magazine publication date, and would be scooped by their rivals.
A bit of a stalemate ensued, and eventually the press conference got underway, with everyone in the room of course snapping away with enough digital cameras to make it look like the red carpet at the BAFTAs.
We Brits didn't bother - the embargo date was fine by us, and of course we were promised a nice fat press-pack with full product photography.
Only at the end of the conference were we told there was now no embargo, after frantic behind the scenes chatter between various European PRs, and here was our press pack.
Felt surprisingly thin, because of course there was no CD-ROM of nice pictures included. No worries, we were told, you'll get it before we leave for the airport.
That was two years ago. I'm still waiting for the disc...
