An official statement blames "phasing of revenues" for lower than expected earnings, but conveniently doesn't mention the loss of income from YouTube earlier this year. In March, while PRS for Music was renegotiating royalty rates with YouTube, the world's biggest online video service began blocking access to most music videos for UK viewers.
At one point last year YouTube was reportedly responsible for 40 percent of PRS members' video plays. It's hard to imagine that the loss of their royalty payments since March wasn't a major contributor to the revenue decrease.
In May PRS for Music announced new streaming royalty rates, which took effect at the beginning of this month.
The per stream minimum dropped substantially, which should help smaller webcasters. At the same time the basic rate increased to 10.5 percent of revenue from 8 percent.
