You need only to glance at the newspaper stands this morning to realise that the world has gone Royal Baby mad following the announcement last night that the Duke and Duchess of Cambridge had become parents – The Sun has even rebranded ‘The Son’ in honour of the new prince.

The world’s media waited with baited breath for news from the Lindo Wing at St Mary’s Hospital in London, but brands across the globe have also been preparing for months to take advantage of the publicity opportunity.

Here are some of my favourites:

Coca-Cola cleverly extended their #shareacoke social media campaign to congratulate the royal couple.

BT lit up the capital last night with a special message.

Interflora made a special delivery to new mum Kate at the Lindo Wing.

Marks & Spencer has created a special ‘Royal Baby Etiquette’ guide on its Facebook page.  

Oreos quickly took advantage of the Twitter storm.

Finally, Air New Zealand delivered a congratulatory message.
