YouTube update hints at pay-to-view channels

YouTube's latest app update for Android appears to support speculation the internet giant is set to charge visitors to view some video.

The update includes code which tells users ' You can only subscribe/subscriber to this paid channel on your computer', according to Android news site AndroidPolice.

Speculation has been mounting that Google is interested in a move to paid channels on YouTube.

AdAge said last month YouTube had contacted a small group of channel producers asking them to submit applications to create channels viewers would have to pay to access.

It appeared the first paid channels would cost between $US1 and $US5 a month, it reported.
