A slew of new offerings that enable consumers to watch concerts online - live in some cases, free in others -  have been introduced this month by a host of providers.

Social Media Streaming

The night before Thanksgiving, fans of the legendary rocker group KISS will be able to watch the group perform live in Los Angeles through Facebook via its Ustream service. Fans will also be able to connect with each other for real-time chat and live video during the show.

Ustream has been instrumental in leveraging the large audiences on social networks for all kinds of events, most recently "Twilight Saga: New Moon" red-carpet arrivals at the movie's world premiere.

iTunes and Billboard.com

Apple introduced live music to its menu of offerings on iTunes this week (via Wired) featuring downloads of live concerts by about 20 artists who are promoted by Live Nation.

Initially, iTunes will have a section featuring the concerts of singers and bands - from Jesse McCartney to Ziggy Marley - with hundreds more shows in the coming months. Prices will start at about $7.99.

Billboard.com has also recently ventured into this space, with the rollout of a new website that lets music lovers watch free concerts online - with a choice of watching from one of five different camera angles.

Alicia Keys, Usher, David Archuleta, Daughtry, among other artists yet to be announced, will be featured in this initiative.

YouTube Gets in the Game

The month kicked off with YouTube's first live full-length webcast concert: U2 at the Pasadena Rose Bowl (via Wired), bringing in 10 million viewers worldwide in addition to the 100,000 who attended in person. YouTube plans to webcast more full-length shows like the live U2 concert on a case-by-case basis.
