Microsoft's internet service MSN is to cut back drastically its chatroom services because of concerns about child safety, it said.
MSN is closing all its chatrooms in Europe, the Middle East, Latin America and most of Asia from 14 October, and changing the way others are operated globally.
Many retired men and women are attracted to senior chat rooms as a way to be social and interact with other seniors online.
As the Internet becomes integrated into daily life, these chat rooms can provide a vital link to meeting people and continuing to keep the mind active. Many seniors see it as a time to do the fun activities that have been on their minds for years.
For many seniors, the Internet is a tool that can keep them learning and enjoying life using simple technology such as chat rooms.
MSN UK's Matt Whittingham told BBC News Online it was not a decision they had taken lightly.
"We have been concerned about chatrooms for a while and reached a stage where we were no longer prepared to put up with inappropriate communication," he said.
The only chat service available to MSN users in the UK will be the free instant messaging service, MSN Messenger, which is not so open and gives people more control over who they talk to.
Chatrooms on MSN's other global sites will either be supervised - or moderated - by an adult 24 hours a day, or will be on a credit card subscription-basis only.
