El 33 (Catalan pronunciation: [əɫ ˈtɾɛntə ˈtɾɛs]) is Catalonia's second public television channel. It belongs to Televisió de Catalunya, a subsidiary of the CCMA. El 33 began its trial broadcasts on 23 April 1988, and began regular transmissions exactly one year later on 23 April 1989. The channel was originally called Canal 33 until 7 May 2001. In 2003 El 33 underwent a restructuring that split it into two channels that shared the same frequency: 33 and K3; this situation ended in April 2010, El 33 broadcast 24 hours but in October 2012, El 33 now shared its time with Canal Super3, from 21:30 to 06:00, due to the reorganization of certain channels to adapt Spain's ongoing economic situation.
