"This election is the first where everyone who's involved in outside broadcast is involved in mobile broadcasting," said Garnett ahead of the event.
"We're using modern forms of broadcasting in a way that we've never used them before. It's hugely exciting.
"We're using Periscope and Meerkat to provide behind-the-scenes coverage from outside broadcasts."
Behind-the-scenes glimpses like these are what sets social media content apart from formal news bulletins, often appealing to a younger, less politically-engaged audience.

The Birmingham Mail, one of Trinity Mirror's titles, recently began upping its Periscope too. Joining forces with Twitter it conducted what is regarded to be a landmark for UK social media: the first Periscope hustings (a local debate) with a constituency's parliamentary candidates.

Of the 650 declarations on the night of Thursday May 7th, Sky News was live from over 270 to provide what it claimed, ahead of the event, would be the most ambitious and wide-ranging results service available.

Sky News has form with this, most recently broadcasting 32 concurrent livestreams from iPads for its coverage of the Scottish Referendum:
