New York-based Jupiter Media Metrix, formed by the merger of Jupiter Communications and Media Metrix last year, said Tod Johnson will remain in his current position as chairman and CEO until the company finds a replacement.
Johnson had been juggling two companies; he is also chairman and CEO of The NPD Group, a privately held market research firm that developed the technology for the original Media Metrix and Digital Media measurement business.
A trail of other companies recently have seen changes in their key management positions. On Wednesday, Yahoo's top ad executive, Anil Singh, stepped down, just a week after Chief Executive Tim Koogle left his role. Koogle plans to continue only as chairman of the Web portal.
Jupiter Media Metrix said its new management structure will support its evolution into a fully integrated measurement and analyst research organization.
"Jupiter Media Metrix has a tremendous opportunity to redefine the research services landscape," Johnson said in a statement. However, "I believe today's market conditions make it increasingly difficult for me to remain as the CEO of two companies."
Johnson said he will remain actively involved as chairman of Jupiter Media Metrix. He will also continue to head The NPD Group.
Jupiter Media Metrix said that as part of its new management structure, its two group presidents, Kurt Abrahamson and Mary Ann Packo, will divide responsibilities. Abrahamson will be responsible for U.S. business and worldwide sales, while Packo will be in charge of international business and worldwide strategic marketing initiatives.
Chief Financial Officer Jean Robinson will have additional responsibilities as the company's chief administrative officer. And Vice Chairman and President Gene DeRose will focus on external market development strategies.
The company said that the new management structure will support Jupiter Media Metrix's key initiatives, such as serving new and existing clients and building the company's brand under a central marketing group.
