The Fox Report
Barry Fox’s technology column
New tech norm
W
e hear a lot about the
‘new normal’ that will follow
the CV lockdown. But even
BC (Before Covid), the face of tech
journalism was changing radically.
I am old enough to remember when
‘official’ departments announced
new radio, TV and telecoms licensing
schemes and services at press conferences where government ministers and
their technical advisers explained the
tech and answered journalists’ questions. The events were often held in
government buildings. Heightened risks
of terrorism brought tighter security.
Eventually, these were replaced by press
releases with a phone or fax number
to contact for ‘further information’ –
which often came late and lightweight.
The audio, video and telecoms manufacturers continued to hold press
conferences, often tied to trade days
at public exhibitions, and hosted press
visits to their headquarters and labs in
far-off lands. Readers must have grown
weary of thinly disguised ‘thank-you
letter’ articles about production lines.
The end of the Hi-Fi and video boom
years left audio and video companies
tightening their belts, and only the consumer electronics giants and computer
games and cellphone companies had
money to burn on jollies for journalists.
Gadget writers
Meanwhile, the tabloid press – and
free newspapers – were breeding a
new genus of writers who describe
themselves as ‘tech specialists’ but are
better by-lined as ‘gadget writers’; they
know nothing about how things work
and ‘review’ new devices with a pretty
picture, ballpark street price and a few
words of off-the-shelf enthusiasm.
I once went to a press event for which
the host company had hired a young
gadget writer as presenter. One device
she showed was a USB-powered cooler.
‘Does it rely on the Peltier effect,’ we
asked. ‘No,’ she said. ‘It’s USB.’
‘Influencers’
In recent years the gadget pages have
been overtaken by online ‘tech’ sites
hosted by a new breed of commentator – the ‘influencer’. A colourful
character with a pretty face enthuses
over new boys’ toys, with a superficial hands-on demo after the bizarre
ritual now known as ‘unboxing’.
These sites are two a penny and free
to view. The hosts earn money from
click-through purchase links and get
to keep, and privately flog off, their
free product samples.
The manufacturers now often stage
party-style launch events with celebrity guests and no opportunity for
inquiring journalists to share questions
and answers in an open forum Q&A.
Influencers no longer need attend unless they fancy a party, because free
samples will be sent by courier to any
influencer who can prove that a lot of
people hit their site. The only loser is
the real-world customer who has no
way of learning anything of significance
about performance or reliability.
An old-school marketing man, who
works for one of the world’s largest electronics companies, confided recently:
‘I was astonished to find that one of
our marketing team is now giving a
new 65-inch OLED TV, worth £3000,
to anyone with 50,000 social media
followers. All they have to do is post
a picture of them with the set.’
Everything online
I recently signed into a ‘New Influencer Ecosystem seminar’, organised
by a ‘new media group’ for ‘Influencer
market agencies’, which are the modern
online equivalent of the advertising
agencies, which traditionally placed
glossy adverts in magazines. Most of the
seminar speakers spouted meaningless
marketing nonsense, but a couple of
more honest articulates revealed how
the technology now routinely built
into computer equipment has been
shockingly abused; facial recognition, location detection and language
analysis help an influencer gather
valuable personal data on ‘followers’
who ‘engage’. The tools are the same as
those used to influence elections and
referendums. Influencers use clickbaiting to temporarily boost their follower numbers by getting people to
click on the offer of a free iPad.
The CV crisis has of course put a
stop to all physical press conferences
and trips. Everything is now being
done on line and it is hard to see how

and when there can be a return to the
old norm of physical events, hands-on
demonstrations, viewing and listening
sessions, big trade shows and lots of
air miles. It’s very likely that many
manufacturers will see this as a blessed
relief from the cost and effort involved
in hosting live events.
Sometimes, as with lockdown webinars organised by satellite company
SES/Astra and the UK’s DTG (Digital
Television Group), online events are useful for sharing market research and hard
technical facts. For instance, the DTG
cited BT’s measurement of lockdown
daytime Internet traffic in the UK as
averaging 5Tbps, with the infrastructure
coping well with peaks of 17.5Tbps.
Content-free content
But other online events have presented
a worrying view of the likely future.
Xiaomi, the Chinese company which
claims to be the third-largest smartphone producer in the world, lockdown-launched a new phone with a
livestream online ‘watch party’. Ahead
of the event Xiaomi claimed, ‘the same
technology as the likes of Apple – for
a much more affordable price’ with a
‘£179 phone to rival the £419 iPhone
SE.’ A bold claim – it takes a lot more
than price to get iPhone users to switch
to Android.
I signed up and tuned in to the Xiaomi
conference on Twitter. The event turned
out to be a half-hour pre-packaged
promo, with a 15-minute forced wait
before a few zippy presentations, some
unboxing with next to no hard tech and
no opportunity to ask questions and get
answers. I asked to try a phone for PE,
but none is yet available for us.
The link may still be active at https://
bit.ly/pe-aug20-xia. If so, you can judge
for yourself whether this is a good way
forward for product launches, or a giant
step backwards for serious journalism.
The good old days
I have resignedly regarded CV lockdown as Nature’s way of telling me
to sort through a lifetime of paper accumulated when researching stories.
Among a mass of tedious documents
on topics like computer error messages,
spectrum allocation, energy policy and
changes to UK telephone numbering,
I found a note from mid-1992. Philips
took a group of journalists from all over
Europe to Paris for a one-day in-andout briefing on the now-forgotten CD
Interactive system that was then in the
pipeline to launch. As a ‘treat’, we were
taken to the then-new Disney attraction.
This is the preface note I wrote to my
editor in New York, verbatim:
Check in at Heathrow 5.45am. The
coach meeting us at de Gaulle airport
fails to turn up. Go by taxi to La Defense.
But no-one from Philips is at the other
end to pay the taxi drivers. Find way
to the roof of the Grand Arche, looking
for Philips people while the taxi drivers
hold passengers hostage. Find someone
from Philips, and go back down again...
Travel to Euro Disney by coach, but
cannot leave cases and press kits etc.
in coach because it is not waiting.
Walk round Euro Disney carrying bags
for an hour or so (time for two rides).
Walk miles back to coach to the airport
to find that it has left, taking two Italians
to the airport and stranding 14 Brits.
Find train station at Euro Disney which
has one of three ticket office windows
open and a queue of hundreds. No one
anywhere to ask advice, so take train to
Paris and, mainly by luck, get connection
to de Gaulle airport. Run with bags to
coach, run round de Gaulle airport and
get last flight home only because take-off
has been delayed by computer failure.
