The Authority seeks this freedom because it has a duty to provide television broadcasting services as a public service for disseminating information, education and entertainment. With this duty placed upon it, the Authority must, whenever it thinks it desirable to do so, put forward suggestions for improving the quality and range of the service it can offer. At the present time, it is suggesting to Government that it can make such improvement possible in two ways: by removing outside restrictions on the length of time during which Independent Television can be on the air, and by the authorization of a second service. These two approaches have a single and similar aim, the broadening of ITV’s range. A derestriction of hours would be of immediate advantage, since it could take effect without any need to wait for fresh transmitters to be built. Its benefits, though substantial, would however not apply to all viewers, but to those who find themselves able to watch television during the day. A second service would enable the programme range to be extended at the times when it matters most—the main evening hours. Both of these changes seem to the Authority most desirable if it is to implement fully the duty laid on it by Parliament—the running of a high quality television service which exploits to the full the potential of the country’s principal mass medium.
