Now that summer is upon us, I thought it would be an appropriate time to honor the concept of the Summer Replacement Show and for folks to list their favorites, both past and present. The concept of a series only running in the summer, usually in place of a regularly run series that had the summer off, has been around since the very early days of network television. It continues today, though in recent history the summer series have been promoted not as seasonal afterthoughts nor just a collection of unsold pilots, as some past threadbare examples were, but as equally polished as any of those run during the rest of the year. Still, whatever the reason, they are presented during a time of year when fewer people are at home and watching television and, one presumes, just were not ready for a more prominent showcase. So what are the ones you remember enjoying the most? I'll start off with the most obvious choice: THE PRISONER, which made its U.S. debut on Saturday nights in the summer of 1968. After that I would vote for CORONET BLUE, which though filmed in 1965, never aired until Monday evenings in the summer of 1967.
