Generic research: technology in the 70s and 80s

I wanted to find out what popular technology pieces were around in the 70s and 80s, the time period I'm contrasting with current day. It is quite a drastic change, as the 1970s was almost 50 years and change in technology since has been phenomenal. I found a page on BBC Four's website noting popular pieces of technology in three time frames.

These pieces of technology have evolved largely in the last 40 years, with TVs being thinner and wider now, and CDs and VCRs are not really being used much anymore. Some of this technology has been almost eradicated from usage; some has evolved to be smarter and become, as a result, more popular. For example, computers now are more efficient and faster than they were in the 1980s. The technology above was a large part of my older interviewees lives; not so much for the current teenager interviewees.
