Mercora is a social music network based in Silicon Valley, California. Mercora allows Internet users to search and listen to a digital radio network of over three million songs, express their musical identity via a customizable profile page, and webcast music to friends, family, and other Mercora users.

Mercora's mission is to catalogue and organize the world's music and make it universally searchable and legally listenable. Mercora is free.

Mercora allows music lovers to express their musical identity to friends and family via a customizable profile page. Users can create musical profiles, upload digital pictures, and listen to and webcast their favorite artists. By webcasting, users can share their music with friends, family, and other Mercora users worldwide.

A Mercora user can discover new music by viewing recent searches, listening to webcasts, exploring hot mixes, or browsing the profiles and collections of other Mercora users. A user can also search for artist biographies, discographies, reviews, images, and podcasts. Mercora users can also communicate and share their musical tastes via charts, messaging, and chat.

At present, Mercora's catalogue contains over three million unique songs. The songs are streaming only (no downloads) and free. Mercora's catalogue includes over 200,000 individual artists across all music genres from alternative to dance, rock to hip hop, and classical to jazz.

At present, Mercora offers two options for Internet users:

If a Mercora user simply wants to listen to music, he can search the Mercora network via Internet Explorer and click on a song link to listen. No software download is required.

Additionally, if a Mercora user also wants to webcast his music to other Mercora users, he can download a software client that webcasts music from his personal music collection to other Mercora users worldwide. This software client contains no adware or spyware, will not interfere with other music players, and is free.

Mercora IMRadio Mobile provides users with wireless access to the Mercora network. IMRadio Mobile users can search and listen to a digital radio network of over three million unique songs and 200,000 individual artists.

IM Radio Mobile offers support for any Windows Mobile 2003-based Pocket PC or Pocket PC phone with Wi-Fi, GSM or GPRS (3G) connectivity. Windows Mobile 2003-certified devices include Pocket PC by Hewlett-Packard and Dell and Pocket PC phones by Hewlett-Packard, Siemens, Samsung, and Audiovox.

• AOL Instant Messenger
• Google Talk

Mercora Madwords is a contextual advertising system that enables advertisers to target text placements by artist or music genre. The text placements are displayed in the "Sponsored Links" section of a webpage upon a search for artist or genre (such as "Coldplay" or "Alternative"). In some ways, this system is similar to Google AdWords.

Madwords enables advertisers to sign up directly via a credit card and is priced on a pay per click (PPC) basis. Advertisers can create and upload their text ads, select their targeting criteria, set their budget and PPCs, and view statistics and reports via a password-protected webpage.

Mercora Search Boxes enable consumers to search and listen to music from websites and blogs. Website and blog operators can customize the search box to incorporate their desired color scheme, size, logo, and preferred artists (such as "Radiohead"). Consumers can search for artists and listen from a separate browser window.

Mercora Music iFrames enable consumers to view a subset of songs available from a particular artist and click a song to listen. The list of songs is dynamically generated and updated every 60 seconds. There is also a 'more' option if the consumer desires to listen to a song that is not currently displayed within the Music iFrame. Clicking the 'more' button displays a full list of songs available from a particular artist.

Similar to Mercora Search Boxes, website and blog operators can customize the Music iFrame to incorporate their desired color scheme, size, logo, and preferred artists.

Mercora IMRadio v5 requires Windows 2000/XP/2003 Server and a broadband Internet connection. In order to support webcasting, audio files must be in Vorbis, MP3, or WMA formats. The application has a file size of 2.53MB.

In 2006, Mercora expects to migrate to a browser-based model which will enable support for the Mac and Linux platforms.

Mercora was founded in 2003 by Srivats Sampath (president and CEO) and Atri Chatterjee (vp of marketing and business development).

Before founding Mercora, Srivats Sampath was co-founder and president of McAfee.com, vp of server product marketing at Netscape, and president and CEO of Discussions Corporation.

Atri Chatterjee was previously vp of marketing and business development at McAfee.com, vp of marketing at Responsys, and director of server marketing at Netscape.

At present, Mercora still has several areas for improvement. While the Vorbis-powered audio streaming technology offers very good sound quality, it can also result in periodic buffering issues.

Secondly, since the majority of Mercora users are from the U.S., Canada, and Western Europe, there is a greater selection of popular music from Western countries and comparatively lesser amount from Middle Eastern and Eastern countries.
