Loved this video where Mary Meeker shares the internet trends that she shared in May. Though this is a bit dated (delivered in May 2018) but still highly relevant if you are planning to do anything on the internet.
I would recommend that you watch this and internalise the trends. You might have to watch it more than once, as she goes at an unbelievable pace and covers a lot of ground in 30 mins.
Mary is an American VC and a partner at the venture capital firm Kleiner Perkins Caufield & Byers. She focuses on Internet and new technologies.
Enjoy the video.
