The sales followed a bumper year – one in which it saw pretax profits rise 30% to £435mln.
ITV is now more than three-and-a-half years into a five-year turnaround plan, introduced by chief executive Adam Crozier.
This has included cost-cutting and acquisitions, as well as diversifying the broadcaster's revenues away from an overwhelming dependence on free-to-air advertising.
It took £28mln from its overheads last year and will make a further £10mln of costs cuts in 2014.
During 2013, ITV acquired The Garden and Big Talk, in an effort to up its factual entertainment and comedy formats. And in the US, a key market for growth, it bought Thinkfactory Media and High Noon Entertainment.
The stock has advanced 47% in the last year.
Crozier was the biggest seller of shares after exercising options under the 2012 performance plan.
He banked £3.16mln, while finance director Ian Griffiths sold just over £2mln-worth.
