On 27 July 2010, the House Of Lords confirmed plans to launch an inquiry into the television advertising market, which "paid particular attention" to the CRR mechanism. The Lords committee investigated the declining revenues that commercial broadcasters gain from the sale of advertising across their networks. The members also considered possible changes to current ad market regulation, including the CRR system, product placement rules, and the scheduling and sale of advertising. The committee wanted to hear evidence on the current levels of regulation, and what impact a relaxation of the rules could have had on the commercial broadcasting sector. Interested parties submitted written evidence to the inquiry on 24 September 2010, with oral evidence been heard in October. A written report was expected to follow in late 2010 or early 2011.
