"WhatsApp is worth more than what we paid for it," its founder said on Monday Facebook Mark Zuckerberg, defending his choice to make one of the biggest acquisitions in the history of the technology industry.
The popular online dating appchangeof messages, photos, videos and audio files was purchased last week from Facebook against 19 billion dollars.
Speaking at the Portable Technologies Exhibition Mobile World Congress in Barcelona, the Mark Zuckerberg said that price that agreed to pay to acquire the application "was justified" because, with about 450 million users, "WhatsApp is one of the few services that could someday reach one billion users."
Earlier, WhatsApp announced that as of April this year, it will offer free phone calls over mobile phones.
To date, the application offers the ability to record and send instant audio, but not live conversations in the form of telephone conversations.
