 Prior to the launch of "E4 Music", E4 was off-air during daytime for much of the year, only going on air in daytime for rolling coverage of reality series such as "Big Brother".In 2008, the launch of 4Music as a channel led to questions being asked about the future of "E4 Music".However, E4 retained its commitment to music content, stating that "E4 Music" had been commissioned to run until at least the start of "Big Brother" in 2009.
