00:00:01,190 --> 00:00:02,720
- [Instructor] In this
and the next two videos,

2
00:00:02,720 --> 00:00:06,770
we're going to introduce
the Twitter streaming API

3
00:00:06,770 --> 00:00:11,140
and demonstrate how to access
the live stream of tweets.

4
00:00:11,140 --> 00:00:15,200
So the tweet stream that you're
going to be able to access

5
00:00:15,200 --> 00:00:18,710
is going to give you a
randomly selected subset

6
00:00:18,710 --> 00:00:23,710
of the live tweets up to a
maximum of 1% of the live tweets

7
00:00:24,120 --> 00:00:26,620
that are coming in throughout the day.

8
00:00:26,620 --> 00:00:30,290
Now according to the website
internetlivestats.com,

9
00:00:30,290 --> 00:00:32,790
as of the day of this recording,

10
00:00:32,790 --> 00:00:36,690
Twitter is getting about
8,500 tweets per second

11
00:00:36,690 --> 00:00:41,600
which works out to almost 3/4
of a billion tweets per day.

12
00:00:41,600 --> 00:00:43,900
And given that, that means you have access

13
00:00:43,900 --> 00:00:45,280
for free right now

14
00:00:45,280 --> 00:00:49,910
to as many as possibly
7.5 million tweets a day

15
00:00:49,910 --> 00:00:54,910
and that's already up by 50%
since we published this book

16
00:00:56,020 --> 00:00:59,730
on which these videos are
based just a few months ago.

17
00:00:59,730 --> 00:01:02,220
So I think when we first wrote about this,

18
00:01:02,220 --> 00:01:05,730
it was probably about six
months ago and at the time,

19
00:01:05,730 --> 00:01:09,240
there were approximately
5,000 tweets per day.

20
00:01:09,240 --> 00:01:11,590
And of course that's going to vary daily

21
00:01:11,590 --> 00:01:14,470
based on what's going
on in the world as well

22
00:01:14,470 --> 00:01:16,060
so it does go up and down

23
00:01:16,060 --> 00:01:18,000
but these are the current numbers

24
00:01:18,000 --> 00:01:20,610
as of the day I'm recording this video.

25
00:01:20,610 --> 00:01:22,940
So you have access to an absolutely

26
00:01:22,940 --> 00:01:24,950
massive number of tweets.

27
00:01:24,950 --> 00:01:28,970
And of course if you're
accessing the live tweet stream

28
00:01:28,970 --> 00:01:31,040
looking for a specific topic,

29
00:01:31,040 --> 00:01:34,070
then the total number of
tweets you'll have access to

30
00:01:34,070 --> 00:01:37,930
will be a subset and
possibly a small subset

31
00:01:37,930 --> 00:01:40,903
of those 7.5 million a day.
