Here's a more in-depth article from The Guardian:

The Gremlins, the trouble-making critters that terrified smalltown America in the 1980s, have returned after 20 years to wreak havoc on Dragons' Den star Peter Jones in a TV ad for BT.
In the ad, which was created by ad agency Swarm, Jones is seen working alone late at night in his office.
As he struggles with computer problems and finds frayed and chewed wires, the Gremlins sneak around the office destroying all the IT gear.
With no IT support, Jones's office rapidly descends into a Gremlins free-for-all complete with fan-swinging antics by the critters.
Mick Hegarty, the marketing director of BT Business, said the company chose the anti-hero Gremlins because although "everyone loves them", there is "nothing worse than gremlins attacking your IT system and damaging your work".
Special effects company Artem created the 20 creatures for the ad, which required 28 puppeteers and technicians to operate the Gremlins and 100 litres of liquid latex and 75 litres of soft foam to make their bodies.
BT, which licensed the use of the Gremlins from Warner Bros, will also feature them in print, poster and online advertising during the eight-week campaign.
The ad, which breaks on May 5, promotes BT Business's 24-hour IT and communications support for its business customers.
Jones has replaced Gordon Ramsay as the face of BT's TV campaign promoting its business telecoms services.
The darkly comic film Gremlins took the world by storm when it launched in 1984.
In the film, Billy Peltzer is given the Christmas gift of a small cuddly creature called Gizmo that he must care for following three simple rules: no water, no food after midnight and no bright light.
When he breaks these rules Gizmo spawns a bunch of nasty, mean creatures, led by Stripe, that terrorise the town of Kingston Falls.
The film - which launched with the marketing strapline "Cute. Clever. Mischievous. Intelligent. Dangerous" - was executive produced by Steven Spielberg.
A sequel, Gremlins 2: The New Batch, appeared in 1990.
Though I have to say, as cool as this is, BT is one of the worst service providers when it comes to getting gremlins in the system, as the frequent problems our office has with Internet doubly proves...
