Tandberg has some of the most beloved products in the video channel, and a strong -- if not always happy -- network of channel partners. Though much of its video gear is high-end, Tandberg has in recent years started to push downmarket, challenging its rivals on price points and bringing itself within range of midmarket budgets for the first time. All the while, it's overtaken Polycom to take by what most estimates say is the No. 1 market share for video endpoints and video infrastructure products. No wonder Cisco -- expected to finalize its acquisition of Tandberg by the end of April -- took such a shine to them.
