TV stations Nine and Ten will begin delivering free Electronic Program Guide (EPG) information from today, which will work with compatible TV and digital receiver products.
The EPGs will offer up to seven days of programming information, which consumers will be able to display on their TV screens if they own the correct equipment.
Seven says it will begin delivering the service from 1 January 2008.
Prime and NBN say they will also commence their EPGs from today, with Southern Cross to join the pack on 26 November. WIN has already commenced.
