This autumn, hit40uk, which runs the commercial chart show, is to introduce the AC Chart, which will target older listeners with mainstream tracks from albums.
A second, urban, chart will aim to capitalise on the growing popularity of hip hop and R'n'B music.
GCap Media will handle the sales and commercial partnerships for the charts and will announce the first sponsor within weeks.
Hit40uk has recruited two additional sales executives and a promotions account handler to drive revenue
The AC Chart will be presented by TV's Melanie Sykes and Heart 106.2's Nick Snaith. Targeting 25- to 44-year-olds, it will air on 54 stations, including the Heart, Real Radio and Century networks. Charting the nation's biggest-selling artists, it will include album and music DVD sales, downloads and airplay.
The urban Fresh 40 chart will focus on R'n'B, hip hop and dance music.
It will run across youth-radio brands, such as the Galaxy, Kiss and Vibe networks, on both analogue and digital platforms.
The development follows criticism that the basis of the singles chart is too narrow and only reflects the taste of a diminishing band of single-buying teens.
It is hoped that the two charts will provide advertisers with a more highly defined audience.
The hit40uk show, which is sponsored by Woolworths, will retain its position as commercial radio's mainstream chart. It will also be expanded by the addition of Emap's Big City network of radio stations, which will broadcast the show when the Smash Hits chart comes to an end in the autumn.
