Boston Legal, the David E. Kelley-created legal dramedy starring William Shatner, James Spader and Candice Bergen as high-flying Boston lawyers, has been picked up for a fourth season by ABC.

The show, which airs at 10pm on Tuesdays, was called a "consistent performer" by the network when its renewal was announced at the March Development Meeting in Los Angeles. ABC added that Boston Legal "generates an extremely upscale audience" and is the number one show in America "based on the concentration of high income viewers in its young adult audience," that is adults aged 18-49 with $100,000 or more in annual income.

Boston Legal airs in the UK on Living.
