There’s a debate here, clearly – but I think there’s a difference between manufacturers sending you written or video material and inviting you to go on a launch where you’re free to make your own decisions.
Also worth adding that if it’s (for instance) a new videogame or pharmaceutical, flying a load of writers/journos/doctors/etc. somewhere warm and sunny would be a blatant attempt to sway positive coverage, but when it comes to doing a global bike launch with journalists from all over the world, good riding destinations make a lot of sense and you’re hardly going to fly them to Swindon instead.
The Scalpel launch last week in Italy had around fifty journalists (of which I was one) from all over the world, and doing that has it’s own economies of scale compared to doing a launch in each country. It was all paid for by Cannondale, but as Barney says, we’re allowed to write and photograph whatever we want in these cases. It’s not a matter of just being spoon-fed content by a third party.
