Best B2B examples of content marketing?

[Fiona Beyond Bamboo]

Hi,

I'm planning to pitch for a project where I sell in doing some content for a FTSE 100 client, B2B. However, often corporates are wary of the benefits of content strategy and like to see tangible examples of where other corporates have done well. Have any of you spied some great case studies from corporate sectors? Or failing that from Gov, NGO, Charities etc?

So far I have:

- Arup thoughts

- Anglo American

- M&S and Plan A

- Unilever

Thanks

Fiona
