A Christmas advert for the Polish ecommerce site Allegro has had 4 million views in just one week. The 3-minute long video shows an old man preparing for Christmas by learning English, using a book from the site that has been delivered to his house. The heart-warming reason he is learning English is revealed at the end of the video, and has caused the video to go viral. Allegro said in an interview with Buzzfeed that it has “strived to make both Allegro… as well as our communication to customers bring joy, touch the heart and cause a smile”. It also added that they aimed to show a simple story that could be understood “by any other nation or community” outside Poland.
