Mr. Frommer changed the industry profoundly, Roger Dow, the former chief executive of the United States Travel Association, an industry group, said in an interview for this obituary in 2014.

The Dow Jones Industrial Average, the S&P 500 and the tech-focused Nasdaq Composite closed at record highs last week, with most stocks edging upward this week following a pause on Tuesday.

Dow Jones, the parent of the Wall Street Journal, reached a licensing deal with OpenAI in May that could be worth more than $250 million over five years.

The S&P 500 rose by 3 percent on Wednesday; the Dow Jones Industrial Average, by 4 percent.

In early trading, the Dow Jones industrial average surged more than 1300 points, or about 3%, with expectations that a second Trump presidential term will bring major policy changes, including more tax cuts, more deregulation, more mergers and acquisitions and more domestic crude production.
