KT's broadband business, a traditionally high-growth business that's doing about 3 billion USD, is largely considered to have reached its peak last year.
The lesson here: Mobile carriers might soon face a similar situation as the one KT is in now. That is, rather high revenues but very slow growth. Mobile data revenue is already stagnant. We'll see how things will turn out for wireless carriers.
PS. Team Korea is having its first match of this worldcup against Togo tonight. Go Korea !
