It looks at how momentous events in history would have been reported through the prism of social media, starting with the Moon landing. Though it captures with a sly wink the vacuity and self-promotion inherent in any timeline, almost the first hashtag used, for a picture of a cat with its head stuck in an upturned fishbowl, had me grinning like an idiot.
The general population of tweeters might get it in the neck, but so do monolithic corporations trying to take advantage of the social media audience - the embedded BBC vox pop video is a perfect pastiche of the punning, plummy-voiced reporters of the 1960s venturing out among the masses.
Obviously with such a global event on social media, there is only way for the programme to end - with the aural equivalent of a whale on your screen. Typical.David Crawford, Radio Times, 19th February 2014
