According to the map , the highest percentage ownership rate of television is found in

The answer is North America!

You didn't show us the map you were looking at, so I've attached one (below) from Wikimedia Commons.   The map shows darker colors where television usage is the heaviest.  So yes, as the other answer pointed out, the highest rate of television ownership/usage is in North America, particularly in the United States.

the vast majority of ballots have been counted nearly two weeks after one of the biggest political upsets in modern u.s. history catapulted donald trump to the presidency.

estimates show more than 58 percent of eligible voters went to the polls during the 2016 election, nearly breaking even with the turnout rate set during the last presidential election in 2012, even as the final tallies in states like california continue to be calculated, according to statistics collected by the u.s. elections project.

but among those figures were stark contrasts in key states that swing the election to trump — in ohio, wisconsin, iowa, michigan and elsewhere — indicating the president-elect’s leap from long-shot candidate to the most powerful political position in the world may have happened in part because of apathy toward hillary clinton’s candidacy, especially among the democratic base, several political scientists and organizations monitoring voter turnout told the pbs newshour.

while clinton is leading the popular vote by more than 1.5 million over trump as of sunday, she trails president obama’s 2012 totals by more than 2 million ballots — a chasm that may have cost her the election, said david becker, co-founder of the center for election and innovation and research.

“several million voters didn’t come out to vote,” becker said. “which is telling me that this idea of the trump wave, a huge number of voters shifting over to trump, is certainly not the story.”
