Biola Alabi is going to study at Yale University for five months and won't be returning to M-Net.
"After her Yale fellowship, Biola Alabi will pursue new career opportunities," says M-Net in a statement.
"We wish her every success in what will certainly be a glittering career," says M-Net Sub-Saharan CEO Patricia van Rooyen in the statement.
Biola Alabi joined M-Net in 2008. Her job focus changed at the beginning of 2014 when her job title was amended to that of M-Net Africa managing director for special projects.
In this capacity she was tasked to look after projects such as the AfricaMagic Viewers' Choice Awards, reality productions such as Big Brother Africa and the AfricaMagic Original Films project.
During Biola Alabi's tenure at M-Net she oversaw the launch of the AfricaMagic Hausa, AfricaMagic Yoruba and AfricaMagic Swahili TV channels on MultiChoice's DStv and the expansion of the AfricaMagic brand to eight TV channels.
She also presided over four editions of Big Brother Africa, as well as the Face of Africa model reality show in 2010.
