The Gazettes are the official paper of the state, essentially, and record a remarkable amount of useful information for family history research - notices of businesses, bankruptcies, military honours and promotions, civil awards, planning permissions, and much more. 350 years of publication is certainly worth celebrating!
The Gazette website has a dedicated section looking back at the title, available at https://www.thegazette.co.uk/history/350-years. As part of the celebrations, the site has uploaded a short animated video at https://youtu.be/JqK2Lx6mryI, presented below for convenience:

Note that the Belfast Gazette replaced the all Ireland Dublin Gazette as a new title for Northern Ireland from 1921. I recently discovered that 50 years worth of the Dublin Gazette have also been digitised for the late 18th century - for more on this, see my blog post from August at http://britishgenes.blogspot.co.uk/2015/08/the-dublin-gazette-from-1750-1800-is.html.
Congratulations to the London Gazette - and onwards and upwards for another 350 years!
