A BBC spokesman said: 'The BBC will respond to Ofcom's long-term propositions once we have had time to fully explore the evidence put forward.'
ITV Broadcasting chief executive Mick Desmond said: 'For viewers, soaps and sport have as much of a role to play as the more traditional public service genres like arts and religion.'
Ofcom will now give TV companies and viewers the chance to comment on its findings.
In the autumn, it will make recommendations to the Government on how TV can be improved.
