ΔRebekah Horne is the Australian head of MySpace, and Vice President of Fox Interactive Media. She also oversees the IGN, Rotten Tomatoes and Ask Men websites.

Last night she spoke to Mike Walsh as part of the Fourth Estate Domain “On the Couch” interview series, in Sydney.

Here’s some of what we heard.

• Yes, Rebekah Horne has a MySpace profile, and refers to social networking rival, Facebook, as “the other site”, or “F Book”…

• MySpace memberships grew six per cent in March compared with 3.6 per cent growth for Facebook.

• There are some 40,000 Australian bands on MySpace, both signed and unsigned acts.

• MySpace widget, or application, developers have been guaranteed recompense for their work, being the revenue generated from ads associated with their widget.

• Australia is a great market for creative content producers, but producing a video series for Web TV, such as quarterlife, is still expensive, and it can cost in the order of $200,000 to produce a series of three to five minute “webisodes”.

• The recently launched MySpace TV is interested in hearing from creative content producers who have ideas.

• MySpace Mobile is “going gangbusters” receiving two million page impressions out of a total of one billion impressions for mobile.
