A new generation of video upstarts are challenging YouTube, drawing users who are seeking nimbler alternatives such as Socialcam and Viddy, reports Reuters.

"YouTube is so inundated with singers and artists and people trying to become the next big star, it’s really difficult to get noticed on there," said 24-year-old L.A. musician Felice Lazae, who previously promoted her songs on YouTube. She called her experience on Socialcam "amazing. It feels immediate."

Socialcam, which is less than one year old, is a video-sharing social network that allows people to upload from their iPhones.

Socialcam has drawn investors such as "Two and a Half Men" star Ashton Kutcher and Tim Draper of Draper Fisher Jurvetson, the story notes.

Viddy, which has more than 26 million users, limits users to 15-second uploads, which can be crafted into sleek vignettes the story says. It has attracted users such as singer Shakira and actor Will Smith, the piece adds.

The report notes: “Lazae has no plans to abandon YouTube altogether. Instead, she spends hours every day maintaining her handful of social media accounts. But as YouTube matures as a repository for established artists and record labels, viewers may turn to sites like Socialcam for raw and viral content, she said.”

Lazae added: "YouTube is still the monster. … But people are constantly wanting to get stuff no matter where they are. If Socialcam keeps going in the direction where it’s easy and accessible on the go, it’s definitely a possibility that it’ll eat into YouTube."
