Since its inception in 1948, the IEEE Signal Processing Society (SPS) has evolved in pace with the many technological changes and advancements in our field. In its early days, our Society— the first and oldest among the IEEE’s Societies—was known as the Profes- sional Group on Audio of the Institute of Radio Engineers.

When you receive this issue of IEEE Signal Processing Magazine, a symposium, “The Future of Signal Processing,” was just held at the Massachu- setts Institute of Technology (MIT). The symposium honored the career of Prof. Alan Oppenheim as one of the pioneers in signal processing research and education. Attendees from various organizations around the world discussed and shared insights of the profound roles that signal processing have played and envisioned the future trends of signal processing.
