Aleks Krotoski returns with a new series of explorations of our digital world.

In the first in the series Aleks looks at how different cultures are preserving their identity in the face of the homogenising effects of technology.

There's a fear that the digital world will make us all the same. But that doesn't seem that well founded if you look at how widely differing cultures are using technology to express their identity and values. We look at the music sharing culture of Mali in West Africa as explored by musicologist Chris Kirkley and hear from the vibrant and intoxicating atmosphere of the mobile phone music market in Mali's capital Bamako. Back in the UK we look at the interesting way immigrant communities maintain their cultural ties through technology and the unexpected effect this has on the growth of immigrant communities.

Aleks also talks to explorer in residence Robin Hanbury-Tenison about his thoughts on how technology might be undermining cultures. Does he see the spread of digital as a new form of cultural imperialism?

Other areas of the digital world to be explored in this series include:

How opinion and influence spread in a digital world

What all this new technology means for how we learn?

Do we always know what technology is for and ultimately what it wants?

Has the digital world changed our perceptions and discussions of death?
