The move follows a comprehensive review of the business by senior management. All of Teletext's TV services will cease to broadcast.
Teletext's Holidays and other commercial services on Freeview channels 101 - 107 will continue to broadcast.
The group's travel websites, such as price-comparison site TeletextHolidays.co.uk, travel retailer Thisistravel.co.uk, and booking site Villarenters.co.uk will continue to run.
The company said the TV service was not generating any revenue. It said ceasing its loss- making television activities will allow investment in its travel businesses to accelerate.
The network of individually-profitable travel sites, established by Teletext in recent years, currently account for almost 40% of the company's revenue.
Teletext's Group Managing Director, Mike Stewart, said 'We investigated and researched every means to keep the news service going, but in the end we couldn't find a viable option.'
The volume of commercial activity generated by the TV service has fallen sharply, with revenue declining by 50% since 2003. As a result Teletext's television services have been loss making for the last three years.
The company blamed the decline in the financial performance of the television services on the government's allocation of broadcast capacity for the public teletext service in the 1996 Broadcating Act. Around 70 staff are at risk of redundancy.
