“…4G
to me and our people, it's a game changer. …I see it as the growth [move] all the way and
…I think it will give us a tremendous amount of growth going forward.”

USA
• Continue to bundle with
internet access
• Match webmail providers’
innovations to limit their
market share
• After trying to push their own
solutions, carriers are now
partnering with leading IM
providers
• Still dominated by
independent companies
but consolidating
• Isolated initiatives to
transform the homepage
activitiy
• Consolidation by media
companies
• No significant initiative apart
from SK Telecom’s
acquisition of Cyworld and
BT’s failed bid of Bebo
