It’s back to the future! According to Forbes.com, CBS, NBC and Sony are plumbing their vaults and posting episodes of long-extinct TV crowd-pleasers online. On offer will be whole seasons of Star Trek, Melrose Place and Hawaii Five-O from CBS; episodes of Miami Vice, The A-Team, and Kojak from NBC; and, from Sony, shortened versions of Charlie’s Angels, The Partridge Family and Starsky & Hutch, among others. But beware. These days, watching My So-Called Life, which has been running on ABC.com since December, might make you question why you cared so much about Angela in the first place.
