The English know what they’re talking about when it comes to VoIP (Voice over Internet Protocol). Results of a survey by Harris Interactive show that 46% of the English know what VoIP is, or already use it. That’s significant. In September, a survey by Verizon showed that 10% of Americans gave low-carb vodka as their response when asked what VoIP stood for. In the Harris Interactive survey, which also covered the United States, the number of Americans polled who knew what VoIP is had increased from 36% to 51%.

Even while the number of English in the know is on the rise, a large section of the population—41% compared with 26% of Americans—has no idea what it is.

On another note, men are more informed on the subject than women: 57% of men had heard of VoIP compared with a mere 28% of women. In the United States, the gap is also significant: 34% of women compared with 62% of men.

When asked to name market leaders, the English are quick to respond despite increasing competition in their country. They name Skype and British Telecom (whereas Americans name Vonage). Nonetheless, the gap between men and women persists. Both sexes, however, are equally familiar with standard providers, naming Yahoo and AOL.

Among adults still not using VoIP, more half claim to be interested (56%). However, only 11% claim to be very interested in making phone calls via the Internet. In the United States, the numbers are nearly identical: 49% compared with 11%.
