Virgin Radio finished the week of April 15 as the top Web radio station based on hours streamed. MeasureCast said the London-based broadcaster streamed 303,100 hours of entertainment to 52,161 people.
JazzFM, the previous week's top Webcaster, came in second; classical stations WQXR(FM) and KING(FM) were third and fourth.
The MeasureCast Internet Radio Listening Index remained essentially flat, losing a fraction of 1 percent.
Clear Channel Worldwide continued as the top-ranked network of Web radio stations measured by MeasureCast, by streaming 1.6 million hours to 264,000 listeners.
"There is no doubt that consumer demand for Internet radio is growing," said MeasureCast CEO Ed Hardy.
