A panel of executives from five major and indie labels said they now take a cut of artist ancillaries such as touring to make up for a decline in CD sales.

Though some artists have resisted that encroachment, label heads said searching for other revenue streams was "a question of survival," as Universal Music Latino president John Echevarria said during today’s (Oct. 3) Billboard Regional Mexican Summit in Los Angeles.

The hit in physical sales hasn't yet been significantly offset by digital and mobile, but ringtones in particular are a fast growth area, said Venevision International music VP Jorge Pino.

Pino estimated mobile and digital products -- mostly in regional Mexican -- account for about 8% of the label's business, thanks to Venevision's affiliation with prepaid mobile content provider Movida.

Echevarria and Machete Music president Gustavo Lopez each put their mobile and digital take at about a fifth of their revenue, with success at digital even influencing selection of radio singles, Lopez said.

Back catalog, more so than current priorities, are the big digital sellers for Balboa Records, said GM Adriana Rios. She estimated her label's new media makes up less than 4% of sales.
