A Labour MP has called for a new law requiring Six Nations fixtures and UK test matches to be permanently free-to-view - saying the move would make the sports more "sustainable".
John Spellar argues that youngsters are missing out on rugby and cricket because of the cost of subscription channels.
He wants to see the Broadcasting Act amended so that test matches played in the UK and Six Nations rugby union games involving home nations are available on free channels.
Although the Six Nations has this year been screened by ITV, there is currently no legal requirement for it to be shown on non-subscription channels.
Mr Spellar, who represents Warley in the West Midlands, told The Mirror: "The fundamental thing is we're going to get youngsters interested in sport they've got to be able to see it easily and readily.
"It may in the long term generate more revenue. I would argue that for cricket, kids in particular who aren't engaged in the sport are a potential market."
And he continued: "The position of the TV companies and sporting bodies is 'let's make as much as we can, but my view is this will make it more sustainable."
His Broadcasting (Listed Sporting Events) Bill had originally been listed for a second reading on Friday, but is now likely to be discussed in May.
Under the Broadcasting Act 1996, some 'Group A' events such as the FA Cup Final, the Olympic and Paralympic Games and the Women's World Cup must be available live on free-to-air TV.
But 'Group B' events, such as the Six Nations, the Ryder Cup and cricket test matches played in England can be shown live on subscription TV as long as highlights are available for free.
Mr Spellar admitted his bill is unlikely to make it onto the statute book, but said it warrants debate.
Last year a White Paper carried out while Nadine Dorries was Culture Secretary said there were no plans to extend the events which are free-to-view.
It said: "The Government recognises that the sale of broadcasting rights to subscription TV providers generates income for sports bodies, which enables them to invest in their sports at both the elite and grassroots level.
"The legal framework therefore needs to strike an appropriate balance between retaining free-to-air sports events for the public, while allowing rights holders to negotiate agreements in the best interests of their sport.
"We believe the current list of events achieves this."
