Videophone at IFA 1993
Video telephony, like 3D television, is one of those technologies that has been launched and relaunched several times. At IFA in 1993 Deutsche Telekom presented its "Xitel" analog video phone with this oversize model. The phone had a 2.8-inch display and built-in camera. A pair-set cost 1,990 German marks, which was $1,345 at the exchange rate of the time.
