Report
on
Internet
use
When
the
Internet
was
invented
in
1969,
no
one
could
have
known
just
how
much
it
would
change
the
world.
The
world’s
first
website
was
not
built
until
21
years
later.
Now
there
are
more
than
1
billion
websites
online.
There
have
been
great
changes
in
the
way
people
use
the
Internet.
The
Internet
has
become
more
and
more
important
and
is
now
used
for
a
greater
variety
of
activities.
It
seems
more
people
trust
Internet
security,
as
they
are
more
likely
to
shop
online
or
make
online
payments
now
than
in
the
past.
Both
these
activities
saw
big
increases,
from
38%
to
63%
and
32%
to
65%
respectively.
Sample
The
biggest
change
in
the
past
five
years
is
the
increase
in
people
making
travel
bookings
online.
This
increased
from
less
than
10%
to
more
than
40%.
Also,
the
popularity
of
mobile
Internet
use
has
grown
dramatically
in
the
past
five
years.
Moreover,
it
seems
that
people
of
all
ages
have
taken
to
the
Internet.
Around
21%
of
users
are
now
aged
40
or
over,
compared
to
17%
five
years
ago.
The
number
of
users
under
20
has
also
gone
up.
As
far
as
I
am
concerned,
people
will
probably
spend
even
more
time
online
in
the
future.
It
seems
likely
that
people
will
continue
to
do
more
of
their
shopping
and
payments
online.
The
trend
of
going
mobile
also
looks
likely
to
carry
on.

report
