The art world is famously opaque; to outsiders, the value of masterpieces can rise and fall seemingly at a whim. But with collector interest growing across the globe, banks are now looking to make investing in this market easier – without the need for a fine arts degree.

Now valued at $63.8 billion, the global art market is booming. Its biggest trade show, Art Basel, has transformed the cities of Basel and Miami into global cultural capitals. It's now setting its sights farther afield, with the Art Basel Cities project aiming to give smaller cities the Basel treatment.

To showcase the diversity of Rio de Janeiro during the Olympics, Instagram has created Instawalk Rio – a walkable tour of the city’s unique street art scene. It features prominent works created for the Games, alongside murals and collages specifically commissioned by the social network.

With a preference for authentic fan-made goods over officially licensed merchandise, thriving fan art markets like TeeFury are changing how young people support their fandoms. With over 520,000 followers and 750,000 monthly visitors, can TeeFury bring fan art into the mainstream?
