With three galleries of photographs and artifacts that document the history of broadcasting, a computerized catalog of more than 150,000 television and radio programs, and public seminars, lectures, and programs, the Paley Center for Media examines the past and constantlyevolving present state of media. The past is the main draw here. If you want to see a performance of "Turkey Lurkey Time" from the 1969 Tony Awards, for example, type the name of the song, show, or performer into a computer terminal, then proceed to one of the semiprivate screening areas to watch your selection. People nearby might be watching classic comedies from the '50s, miniseries from the '70s, or news broadcasts from the '90s. Possibly the most entertaining part of these TV shows from yesteryear is the fact that the original commercials are still embedded in many of the programs.If ads are your thing, you can also skip the programming altogether and watch compilations of classic commercials.
