If you look at the hourly breakdown, The Tonys held most of its audience throughout going from a 7.8 million in the first hour to 7.6 in the 2nd hour to 6.8 in the final hour.
What this breakdown doesn't give is the details of the audience demographic, which traditionally attracts people who rarely watch commercial Television and are desirable to advertisers.
Overall, however, the Tony Awards will never get a mass audience like the Oscars simply because the awards have little relevance outside of the core group of theatre fans.
THe alternative would be to have what we saw online from 7 to 8: a series of awards and speeches with no production numbers, no "razzle dazzle." And maybe that is what some people here would prefer.
Cast albums are NOT "soundtracks."
Live theatre does not use a "soundtrack." If it did, it wouldn't be live theatre!
I host a weekly one-hour radio program featuring cast album selections as well as songs by cabaret, jazz and theatre artists. The program, FRONT ROW CENTRE is heard Sundays 9 to 10 am and also Saturdays from 8 to 9 am (eastern times) on www.proudfm.com
