It can be argued that the SBS program, Mythbusters on Monday nights has
been the most influential program in viewing patterns on Monday and
Tuesday nights of this week. With Seven dropping Desperate Housewives to return the fourth series of 24, its audience at 8:30pm dropped from more than two million people to around 1.3 million.

Mythbusters at 7:30 again attracted more than 900,000 viewers,
SBS’s highest audience of the week and on Monday night it boosted the
network’s share to 7.8%.

Without Mythbusters or a similar program in the schedule last
night SBS’s audience share fell to 5.2%, a drop of a third in its
Monday night audience share. That 2.6% was up for grabs and on Tuesday
night and went to the four other networks in the following order,
Seven, 1%, Nine, 0.8%, Ten, 0.6% and ABC, 0.2%.

That redistribution boosted the audience share figures of Nine, Seven,
Ten and the ABC on Tuesday night. So rather than take viewers from each
other they were dragged away from SBS, although the presence of the
final One Day cricket game in the Seven schedule from 7:30pm was also a
major destabilising influence on viewing patterns last night.
