Video game giants in $18bn merger
The companies behind Call of Duty and World of Warcraft are merging in a deal which could shake up the global video games industry. Activision and Blizzard have said they will form "the world's most profitable games business" in a deal worth $18.8bn (£9.15bn).
US-based Activision also makes hit console games such as the Tony Hawk series and Guitar Hero. Nine million people pay a monthly subscription to play World of Warcraft.
Blizzard is the biggest player in online gaming and Warcraft is the global market leader of what are known as massively multi-player online role-playing games, or MMORPGs. It is currently owned by the French media group Vivendi.
