Widely considered the best movie in the "classic Trek" series of feature films, Star Trek IV returns to one of the favorite themes of the original TV series--time travel--to bring Kirk, Spock, McCoy, Scotty, Sulu, Uhura, and Chekov from the 23rd century to present-day San Francisco. In their own time, the Starfleet heroes encounter an alien probe emitting a mysterious message--a message delivered in the song of the now-extinct Earth species of humpback whales. Failure to respond to the probe will result in Earth's destruction, so Kirk and company time-travel to 20th-century Earth--in their captured Klingon starship--to transport a humpback whale to the future in an effort to peacefully communicate with the alien probe. The plot sounds somewhat absurd in description, but as executed by returning director Leonard Nimoy, this turned out to be a crowd-pleasing adventure, filled with humor and lively interaction among the favorite Star Trek characters. Catherine Hicks (from TV's 7th Heaven) plays the 20th-century whale expert who is finally convinced of Kirk's and Spock's benevolent intentions. With ample comedy taken from the clash of future heroes with 20th-century urban realities, Star Trek IV was a box-office smash, satisfying mainstream audiences and hardcore Trek fans alike. --Jeff Shannon
Entertainment
The entertainment industry has grown and evolved over the years with music and cinema taking a new form through the ages and so have the technologies that fuel it. Gone are the days of eight songs on a cassette and VCR players with merely two hours of entertainment recorded on a single video cassette. With the advent of computers came digital data storage and hence the birth of DVD/CDs.
Quiet a step back in matters of physical form as these new generation audio/video storage devices hold an uncanny resemblance to the records that preceded the cassette generation. DVDs and CDs today are an everyday household entertainment storage device which has come a long way since the first records and cassettes were distributed commercially.
Notable advantages of DVD/CDs have to begin with the amount of storage space available. These days its possible to burn multiple movies on a single DVD and as far as audio goes if its in a highly compressed format such as .mp3 a single CD can accommodate multiple music albums. These discs are easy to handle, light and portable with no moving devices unlike the tape generation however they are delicate and a scratch on the DVD/CD surface could cause a disruption in the information being read by the player.
DVD/CDs were initially invented to provide high quality audio/video data to a user with the ability to regulate its production however this soon fizzled away with daily household computers gaining the ability to burn data in such formats. The race to curb piracy through such means has not hit a roadblock and DVD/CDs keep evolving with newer encryption technologies in a bid to curb unchecked replication of data spawning newer technologies like Blu-ray discs which seems to be yet another milestone on an unending road of innovation.
