“In an international scale, I am most happy to see the development of Yahoo in Asia. Where we have market share and penetration big enough,” Bartz said via conference call interviews with analysts.

“But with a heavy heart I must say also that Germany is the country where Yahoo can not thrive. There is a long history of development behind Yahoo in there,” Bartz said again.

Bartz also added that Spain is a country other than Germany are also not showing enough good progress for Yahoo.

So any country that would become the center of attention Yahoo to prosper? Bartz ensure that Yahoo would focus on areas with a large Internet users population.

“Indonesia, India, Brazil, Mexico are the countries which became the focus of our expansion. Also some other internet market share of smaller such as Vietnam. We have a strong penetration in these areas,” explained Bartz.
