The research, from TNS and Ebiquity, tops off a sterling year for the supermarket which experienced an 8% year-on-year increase in sales in the three months following Freddie Flintoff's 'Let's Celebrate' Easter ad campaign.
The supermarket, with its agencies DLKW Lowe and MEC, spent £22.7m on TV advertising and £66.2m on marketing, according to data from Ebiquity.
Tesco, which achieved the second spot on the table, invested almost twice as much as its rival in the same period – £120.5m, of which £44.9m was on TV advertising.
Morag Blazey, global practice leader advertising intelligence at Ebiquity, which sourced this year's budget data, said: "Although Adwatch inevitably favours advertisers with a constant television presence, the table shows that memorability isn't just about spend.
"It clearly illustrates the value of a consistent and recognisable positioning, which lets retailers such as Morrisons weave themselves into the very fabric of TV."
