I'm sharing this on here exclusively for the moment, a bit of follow-up data to my blog post that appeared today.
The pie chart shows media requests posted through ResponseSource in the 12 months to 2 May 2013, by request type. (Thanks to +Chris Measures
for requesting this data).
The top five request types are:
Information for an article 30%
Personal case study 20%
Spokesperson or expert 17%
Review products 14%
Competition prize, reader offer or goody bag 10%
It is possible to filter by all enquiry types (as well as sender and media types).
