Swiss advertising sales company Goldbach Group has sold its 67% stake in internet TV platform Wilmaa to Thomas Gabathuler.

The founder and managing director of Wilmaa who previously held 33% of the shares will thereby become the sole shareholder. Financial details of the transaction were not disclosed.

WilmaaGabathuler now intends to push on the further expansion of the internet TV platform and its offerings. As part of a long-term cooperation, Goldbach will continue handle advertising sales for Wilmaa.

Goldbach entered the platform as a 50% shareholder in January 2009. Like its local rival Zattoo, Wilmaa offers live-streams of TV channels as a free-of-charge, advertising-financed OTT service.

In contrast to Zattoo, Wilmaa is not available outside Switzerland.
