Digital media streaming vanguard RealNetworks has commenced layoffs of seven percent of its workforce. An additional seven percent may follow in the coming months. The moves are part of interim CEO Rob Glaser's plan to reduce costs by $45 million as rapidly as possible. The first wave of employees involved in the layoffs were notified today, and the second batch have been notified that their current positions will not be renewed at the completion of work, and they may be reassigned elsewhere if financial conditions improve.
