Denver, Colorado-based NewsGator has added localized versions of its RSS aggregators for Germany, Holland, Italy, Belgium, and Spain, the firm said this week. NewsGator and VNU, a major European technology media firm, said that the two companies will provide co-branded services in those local markets. Both the content and user interface will be localized to each country, with local region-specific RSS feeds provided in each of those regions, and local editorial content. VNU is a publisher of computer-related magazines and online content. NewsGtor provides RSS aggregation software used to read news and blogs, backed by Masthead and Mobius Venture Capital.
