ROK Entertainment Group, a UK-based provider of mobile entertainment services and technologies, has raised $7 million from European institutions in preparation for a public float later this year, the company said in an e-mail release. The new investment comes from an as yet unnamed Swiss institution and brings the value invested in ROK to $70 million.

The company, which also develops technology for the mass-market streaming of TV services to 2.5G/3G mobile devices, aims to deploy 30 subscription-based mobile TV services with selected operators by the end of 2007, and has filed 37 patent applications connected with the delivery of mobile content. The company has grown its staff to 150 and plans to use the cash injection to accelerate the global deployment of its mobile TV services and technologies, before doing an IPO later this year.
