Zuckerberg will unveil the tool on 1 May, US time, on Good Morning America, while chief operating officer Sheryl Sandberg will provide more details in an interview during World News with Dianne Sawyer, the American Broadcasting Company (ABC) said on its site on Monday.
There are few details on the announcement, although ABC has been plugging the segment all week in the US. Zuckerberg will be showing off the tool at the company's Menlo Park, California, headquarters.
