The Internet has enabled freedom of expression worldwide, now reaching into some parts of the world that initially suppressed both technology and free expression. The Internet also allows huge amounts of personal data to be collected in the name of security. This week, World Views explores the balance between privacy, free expression and security with Internet freedom activist Rebecca MacKinnon. Tune in Friday at 4 p.m. (repeated at 6:30 p.m.) for this interview and more on World Views.

Since the unexpected death of Bob Parlocha in March, KGOU's Jazz with Bob Parlocha has been airing Bob's recorded material, with a few guest hosts.

The program provider, the WFMT Radio Network, has now announced permanent hosts for the program Bob founded. Starting July 6, Greg Bridges and Lee Thomas will permanently bring their deep knowledge and passion for jazz to the show. They'll be hosting on alternating nights, voicing their insights and sharing their knowledge from the studios of KCSM in San Francisco, in partnership with WFMT.

Although the name of the program will change to Jazz Network, the show will feature archived recordings of Bob Parlocha, so  his voice and his wisdom will still resonate throughout the four-hour show, Mondays through Thursdays at 9 p.m. on KGOU.
