Management can grant waivers to allow approved shareholders to acquire more than 5 percent of the company. A wave of consolidation hit the game industry since the economic downturn started in 2008, with Square Enix picking up Eidos, Tecmo merging with Koei, Warner Bros. snagging Midway out of bankruptcy, Namco Bandai buying D3Publisher, ZeniMax purchasing id Software, and Electronic Arts laying claim to social game developer Playfish. Notable acquisitions in 2010 include Warner Bros.' pick up of Arkham Asylum developer Rocksteady Games, Sony's purchase of Little Big Planet studio Media Molecule, and Reliance Big Entertainment purchase of 50 percent of Codemasters.
