The Nasdaq Stock Market Inc. announced it has completed its acquisition of PrimeZone Media Network, a privately held, Los Angeles-based firm specializing in press release newswire and multimedia services.

The exchange says that this transaction enables it to offer PrimeZone’s information distribution and multimedia services as part of its Investor Relations and Corporate Communications suite. “PrimeZone’s services will be integral to the suite of services offered by Nasdaq’s Corporate Client Group,” it says.
