The Wall Street Journal reported this year’s surge in U.S. deal making largely has been driven by three sectors: healthcare, technology and telecommunications.

The Journal said further, through the first five months of the year, the value of announced U.S. mergers and acquisition stands at $789 billion, up 57% from a year ago and at its highest level on record; healthcare, technology and telecom deals have accounted for $467 billion, or 59.2%, of that total, according to Dealogic.

According to the Journal, that marks the largest slice of overall deal activity from these three sectors in the U.S. since 1996.
