News Corp's MySpace social network site and eBay Inc's Skype will offer MySpace members free Internet calling services, executives from the companies said, in a bid by both to expand their base of users and revenue.

The two were due to announce the deal on Wednesday.

Skype's voice service will be folded into MySpace's existing instant messaging technology, allowing MySpace members to place free calls to other people on the MySpace and Skype networks.
