‘The Company You Love to Hate” was the cover caption of Fortune magazine’s March 1966 story about Con Edison. The blackout of November 9, 1965 caused many New York City residents to become frustrated with a utility often called “Con Ed.”
 
The phrase ‘The company you love to hate” hasn’t survived the 1960s, although many New York City residents still remain frustrated with Con Edison.

Northeast Blackout of 1965
The Northeast Blackout of 1965 was a significant disruption in the supply of electricity on November 9, 1965, affecting Ontario, Canada and Connecticut, Massachusetts, New Hampshire, Rhode Island, Vermont, New York, and New Jersey in the United States.

24 February 1966, New York (NY) Times, pg. 52:
Con Edison dropped 3/8, to 40 1/8, its lowest price since 1962. Contributing to this performance was a critical article in the March issue of Fortune magazine entitled “Con Edison: The Company You Love To Hate.”
 
25 March 1967, New York (NY) Times, “CON ED CHOOSES U.S. AIDE AS CHIEF: Charles F. Luce, Interior Under Secretary, Due to Assume Chairmanship” by Gene Smith, pg. 34:
Mr. Eble, his close friends reported, was especially disturbed by a major article in Fortune magazine’s March, 1966, issue entitled “Nobody Loves Consolidated Edison” and dealing at length with the utility’s management and its policies. The cover showed a manhole cover and a caption that read: “Con Edison: The Company You Love to Hate.”
   
29 November 1968, New York (NY) Times, “Chief Executive of Con Edison: Charles Franklin Luce,” pg. 46:
When Mr. Luce, whose company faces a strike starting Sunday, came to New York, he announced that his goal was to make Consolidated Edison “the No. 1 utility in the country.”
 
The statement was made with the full knowledge that Con Ed, as it is familiarly known, could count among its most immediate ailments a public image of its stature rivaled by the height of one of its manhole covers. Indeed, the manhole and the image had already been linked in 1966 on the cover of Fortune magazine, where a caption called the utility “The Company You Lov to Hate.”
