The Internationale Funkausstellung Berlin, or more simply IFA, started out as a showcase for new TV and radio technology and has debuted things such as the first cassette tape and first colour TV. And in the years since it began in 1926, it has grown into the largest tech exhibition in Europe. Now, we fast forward to today, where all the big players, including Samsung, Sony and Microsoft, show up to highlight their latest and greatest products... at least until CES in Las Vegas in January.
