Google adds another weapon to its online app arsenal with the acquisition of Marratech’s video conferencing and video new meeting software. The Swedish company will continue to serve and support its customer base and reseller network. Marratech’s cross-platform e-Meeting software creates a virtual office. No terms were disclosed; the small—but potentially loud—acquisition was announced late Thursday after Google’s earnings release and call. Earlier in the week, Google announced the purchase of collaborative presentation company Tonic Systems to add to its net-based office suite. The integration of Marratech with the suite, which is perceived as a direct threat to Microsoft Office, would add another dimension. There’s a brief message at the official Google blog.
