Former Broadcast editor Conor Dignam has had an approach to publish Broadcast, Screen International and Shots magazines agreed by owners Top Right Group.
The Emap media brands will be published by a new company set up by Dignam called Media Business Insight.
Dignam said: "I joined EMAP as editor of Broadcast in 2002 and have led the media brands for over three years so am thrilled to have been given the opportunity to take Broadcast, Screen and Shots to an independent future."
Natasha Christie-Miller, chief executive of Emap, said: "This is a great opportunity for Broadcast, Screen International and Shots to carve out their own successful future under Conor’s leadership. No further Emap restructure or portfolio change is anticipated.
"Emap is transforming into a subscriber-led, content-driven and customer-obsessed multi-channel media business. Our strategy remains to focus our investments on brands that have a high growth potential, in scale industries where we are or can be the number one.
"We are investing particularly heavily in our brands serving the retail, fashion, construction, health and architecture sectors where we are already seeing fast, sustainable return."
