And Finally... Samsung Launches Galaxy S4

The hotly anticipated launch of Samsung's successor to the Galaxy S3 smartphone, was unveiled last night at the Radio City Music Hall in New York.

Globally, Samsung dominates the smartphone market, with analysts estimating that it shipped 63.7m smartphones in the fourth quarter of last year. The launch is believed to deepen competition in the mobile phone market.

"We focused on fun, relationships, convenience and health with the Galaxy S 4," David Park, marketing manager of Samsung Electronics, told ABC News.

Samsung said that from the end of next month the Galaxy S4 would be offered by 327 mobile operators in 125 countries.
