Today as an entrepreneur you have more options.

Skype is easy enough to use so that people don't need to be tech savvy - a lot of users just want to communicate with their friends and family, and they find this is the easiest, cheapest way.

When we started Skype, if you look at analyst reports, no one forecasted it as a big business. Also when Google started, it was not fashionable to be in search. It's not trying to do the obvious - that's the hard part.

You have 1 billion people using the Internet with 200 million of those now using broadband internet connections, so the Internet has become a powerful network. It can carry calls.

And the VCR did the same thing: the movie industry thought nobody would ever watch movies any more.

We also have a conference call feature where up to five people can talk on one Skype call.

Some Internet operators are concerned that video services such as Netflix and YouTube consume lots of the bandwidth on the network. While there is some truth to this, my guess is that the operators wished they could provide the same kind of services with the same success as Netflix and YouTube.
