She has headed up the low-priced airline since 2010, prior to which she was chief executive of Guardian Media Group.
I am looking forward to getting to know all of the people at ITV and helping it make the most of the wonderful opportunities that it has in the future, ' she said. She will be eligible for a bonus of as much as 180 percent of salary and a long-term incentive plan of up to 265 percent of her salary.
McCall, 55, took over at EasyJet in July 2010, joining from the Guardian Media Group where she was also Chief Executive. This, the company said, provides broadly the same remuneration opportunity as to ITV's previous CEO.
"For ITV, we think the move suggests the company is comfortable with its strategic direction but her strong personal links should be helpful in several areas".
McCall will join ITV, the maker of soap opera Coronation Street and reality show Love Island, at a time when advertising is coming under pressure from intense competition from internet services and weaker consumer markets.
Crozier, who has been at the helm of broadcaster for seven years, announced his departure from the company back in May.
As of 08:25 BST, easyJet's share price had lost 0.78 percent to 1,400.00p, underperforming the broader United Kingdom market, with the benchmark FTSE 100 index having climbed into positive territory and now standing 0.41 percent higher at 7,408.50 points. Her experience atop Guardian Media, which owns The Guardian and The Observer newspapers, makes her well suited to tackling the challenges, said Alex DeGroote, an analyst at Cenkos Securities.
McCall is expected to leave easyJet around the end of the year.
"She put Easyjet's passengers and people at the heart of the business". More recently EasyJet has struggled with the impact of Britain's vote to exit the European Union, the collapse of oil prices and a string of terror attacks which has driven a slump in fares.
easyJet is setting up a new Vienna-based airline to continue its operations after Brexit.
