Further cuts back took place in 2005 added with the perceived rising costs of original production and the effects on advertising revenues following the ban by Ofcom on 'junk food' advertising within children's schedules from 2007 and increasing competition from CBBC and countless digital children's channels for new programmes (especially imported cartoons, typically from America). In Summer 2006, ITV closed down its in-house children's production unit, as part of ITV's then on-going process of restructuring ITV Productions, and blaming the closure because of the competitive production environment, though ITV denied any intention of ditching its children's programming from its network schedule. At the end of 2006, CITV's weekday afternoon strand on the main ITV network ceased, making the CITV channel, which had launched earlier that year, the primary outlet for ITV's kids programming.
