It was predicted to be huge — and it was. The first presidential debate between Donald Trump and Hillary Clinton was a killer in the ratings.

Early predictions were that the Trump-Clinton faceoff had the potential to smash viewership records for any live televised event — the 2015 Super Bowl’s average of over 114 million viewers currently holds the title.

Monday’s debate came close to that — but didn’t top it.

However, the event did set a new record for viewership of a presidential debate, drawing 84 million TV viewers, according to final Nielsen figures.

Up until now, the most viewed debate in American history, according to Nielsen, was the Ronald Reagan-Jimmy Carter match in 1980. Nearly 81 million viewers tuned in for that.

Among the individual networks airing the debate, NBC was No. 1 with about 18 million viewers, while Fox News dominated cable with about 11 million.

But it’s a totally different TV landscape now. Back then, debates were only carried by the three major broadcasters — ABC, NBC, and CBS. Viewership was much easier to track.

This time around, the debate was carried on more than a dozen broadcast and cable TV channels, it was streamed across the web, and Facebook and Twitter carried it via their social media networks.

A Trump tweet about China and global warming was the most re-tweeted tweet of the night.

Twitter has already announced the debate was the most-tweeted event of the year, with Trump taking the largest share of conversation from the night — 62 percent. Hillary had just 38 percent of the conversation.

The most-tweeted topics during the debate were the economy, foreign affairs, energy and the environment, terrorism, and guns.

However, TV is still king — during the primary debates, more than 95 percent of the overall viewership came via TV.

In August, Fox News drew a record 24 million viewers to its GOP primary debate, while several other networks also set debate ratings records throughout the primary season, according to Forbes.

And that doesn’t even take into account people watching in bars, offices, or hotels — Nielsen only measures at-home TV sets, notes CNN.

Monday’s debate faced competition from Monday Night Football, airing on ESPN, something that Trump noted before the debate.

While a ratings dip could hurt ESPN, the networks airing the debate reportedly had no trouble selling advertising, even though the 90-minute event ran commercial-free. The Wall Street Journal noted that networks had easily sold out their ad space for immediately before and after the debate, with 30-second spots going for as much as $250,000.
