It's difficult to answer a negative, but if I may offer a view on it: Solidarity's first rose to prominence in 1980, and lasted until 1981 when martial law was declared in Poland (Walesa was also recognised with the Nobel Peace Prize in 1983), and then remained active, but considerably less so throughout the rest of the decade.

Contrast this with the Wall effectively collapsing in one night. It makes for a much better spectacle for news broadcasts, as they can report on a sudden event happening, one that had come to physically embody the Iron Curtain; its collapse was also a symbolic end of Communism in Europe, and made for a nice simple news report.
