Iliffe News and Media, publishers of MK News, has bought out the owners of the official Milton Keynes website, Apollo Digital Developments.
The site mkweb.co.uk was launched in 1998 in conjunction with Milton Keynes Council and has established itself as one of the largest online information portals for the area.
Iliffe News and Media's chief executive David Fordham said: "mkweb.co.uk has established itself as a significant online media player in and around Milton Keynes.
"We anticipate that by combining the resources of the Apollo operation with our existing newspaper interests, we will be able to accelerate the growth of our multi-media business, not only in Milton Keynes, but across many of the other areas in which we have a publishing presence."
The recently appointed head of digital media for INML, Becky Moffat, will also join the Apollo board, and will spearhead the development of Iliffe's newspaper-based websites alongside the Apollo business.
The acquisition of Apollo Digital Development completes a busy year for Iliffe News and Media, following on from three newspaper acquisitions that have also been completed during 2006.
