5. Marratech Web Videoconferencing
Google acquired Web videoconferencing software from Marratech, a Swedish software maker, in April 2007 for an undisclosed sum. Cisco paid a whopping $3.2 billion for its acquisition of competing conferencing software maker WebEx in 2007.
The Marratech solution included a downloadable client and was used by a number of universities, Verizon and the Swedish Police Department and Army.
Google used the software internally, and Marratech killed the product and suspended all of its services on Feb. 19, 2010.
