Snap.com, the Internet portal operated by NBC and CNET is expected to announce today that it has inked a distribution deal with RealNetworks Inc., integrating the portal’s search services and logo onto the Netcaster’s video player and Web sites.

The deal is a coup for Snap.com, because it will benefit from Real’s high visibility, as one of the leading video and audio tools on the Net.

Although neither company would disclose financial terms of the multimillion dollar deal, which marks RealNetworks’ largest distribution deal to date, both companies said they will share revenues generated through ads and e-commerce efforts.

The deal provides a significant boost in traffic to newcomer Snap.com, giving it access to the 60 million Internet users who have downloaded RealNetworks’ product and the additional 160,000 people who download the player each day. Roughly 15.5 million people actually use the player regularly.

Snap.com currently trails Yahoo!, Go, Excite and Lycos in terms of visitors. It was ranked 16th for the month of March, according to Internet analyst firm Media Metrix. RealNetworks is ranked at 18.

Edmond Sanctis, chief operating officer for Snap.com., however, said Snap.com will focus on targeting the 14 million users of high-speed Internet connections in the workplace and at home.

As part of the deal, RealNetworks’ RealPlayer G2 makes Snap.com its exclusive streaming media search feature, enabling viewers to search the Web for audio, video and multimedia programming directly from the player.

The Snap.com-branded player is immediately available for download and upgradeable by clicking on an upgrade icon.

RealNetworks’ RealGuide is integrated into Snap.com’s directory for phone modem and high-speed users. Additionally, Snap.com’s search capabilities will be featured exclusively on all RealNetworks Web sites, including Real.com, RealGuide, Daily Briefing, Film.com and MusicNet.com.

Snap.com announced earlier this month that it will merge its assets with Xoom.com Inc., into an independent publicly traded conglom, NBC Internet.
