The most notable thing I observed was that ranking high in the Global 100 in no way correlates with a strong presence on Twitter. Whilst AT&T (#1 G100) are right up there with almost 12,000 followers (@ATTCustomerCare), NTT (#2 G100) aren't. Indeed the only significnat NTT account I could find was @NTT_America which has 787 followers, and China Mobile (#6 G100) don't appear to have a Twitter account at all.
I then enlisted the help of Klout (@klout) to see who they deemed influential and came up with a top 5 that looked like this:
- AT&T Inc. (#1 G100)
- T-Mobile USA (#4 G100 - Deutsche Telekom)
- O2 UK (#5 G100 Telefonica)
- Sprint (#14 G100)
- BT (#15 G100)
