First goes on sale on 17 May, with TV and regional press advertising and a sampling campaign. Further TV ads and a radio campaign break on 16 May, and there will be a dedicated website.
Emap confirmed the name of Project Jackie last week after Media Week revealed that it had registered the title first as a trademark (Media Week, 28 April).
The magazine will have a cover price of 拢1.20 and Emap hopes circulation will reach between 150,000 and 200,000 copies in its first year.
First aims to provide a female-oriented take on the week's news for BC1 women aged 25 to 44 who do not read newspapers, and promises a less sensational approach than existing real-life women's weeklies.
It will run first-person accounts of big news stories, a weekly photo essay and 12 spreads showcasing the week's best photos from around the world.
Each 100-page issue will also carry fashion and beauty pages, TV listings, puzzles and weather forecasts.
Colin Morrison, chief executive officer of ACP-Natmag, said the new title highlighted the changing readership habits of its target audience.
"This idea of 'news with the boring bits taken out' comes as women are dropping out of the newspaper market, which has led to the growth of the general women's weekly market," he said.
