In 1963, the ITA chairman, Lord Hill of Luton, initiated a review of all the ITV companies following the release of the Pilkington Report, which saw the launch of BBC2 and heavily criticised ITV. This review would review a company's performance, and either grant them an extension to their service licence or replace the company with another in that region. This process was repeated frequently throughout the early life of ITV and lasted approximately ten years. Reviews like this also ensured that the companies maintained their high performance by maintaining the possibility of the loss of their licence. The new licences also included clauses which took into account the promised ITV2 UHF channel, promised to be launched if the Conservative Party won the 1964 general election.
